💥💥💥 What is orthogonal quality of mesh and what is used for ?
Orthogonal quality is a mesh metric that measures the shape and orientation of the mesh cells. It is calculated by comparing the vectors from the cell centroid to the cell centroid of each adjacent cell, and to each face. The closer these vectors are to be orthogonal (perpendicular) to each other, the higher the orthogonal quality. Orthogonal quality ranges from 0 to 1, where 0 means poor quality and 1 means excellent quality ³.
Orthogonal quality is used for various purposes, such as:
- Assessing the convergence and accuracy of numerical methods, such as finite element analysis (FEA) or computational fluid dynamics (CFD).
- Optimizing the mesh size and shape for different applications and geometries.
- Detecting and correcting errors or defects in the mesh generation process.
Orthogonal quality can be improved by using structured meshes, which have more regular and balanced cell shapes than unstructured meshes. Structured meshes can also reduce the computational cost and time of solving complex problems. Some tools that can help create structured meshes are Multizone or Sweep mesh in ANSYS².

Why orthogonal quality is important in cfd analysis ?
Orthogonal quality is important in CFD analysis because it affects the accuracy and stability of the simulation results. Orthogonal quality measures how well the mesh cells are aligned with each other and with the geometry. If the mesh cells are not orthogonal, they can cause numerical errors or instability in the solution process. Therefore, it is desirable to have a high orthogonal quality for CFD simulations.
According to some sources, a good orthogonal quality value for Fluent is above 0.1¹². However, this may vary depending on the problem being solved and the element formulation. Some factors that can influence the orthogonal quality are:
- The shape and size of the mesh cells
- The capture curvature option
- The sweepable part of the geometry
- The meshing tool used
Some tools that can help improve the orthogonal quality are Multizone or Sweep mesh in ANSYS², which can generate structured meshes with more regular and balanced cell shapes. Structured meshes can also reduce the computational cost and time of solving complex problems.

How do I calculate orthogonal quality of a mesh?
To calculate the orthogonal quality of a mesh, you need to compare the vectors from the cell centroid to the cell centroid of each adjacent cell, and to each face. The closer these vectors are to be orthogonal (perpendicular) to each other, the higher the orthogonal quality. Orthogonal quality ranges from 0 to 1, where 0 means poor quality and 1 means excellent quality ³.
There are different methods and tools that can help you calculate and improve the orthogonal quality of a mesh. For example, you can use MATLAB's meshQuality function ⁴ or ANSYS's Mesh Metrics ⁵ to evaluate the shape and orientation of the mesh cells. You can also use ANSYS's Multizone or Sweep mesh features ² to generate structured meshes with more regular and balanced cell shapes.

How to improve orthogonal quality of mesh on Ansys Workbench?
Orthogonal quality of mesh on Ansys Workbench is a measure of how well the mesh cells are aligned with each other and with the geometry. A high orthogonal quality means that the mesh cells are close to perpendicular to each other and to the faces. A low orthogonal quality means that the mesh cells are skewed or distorted, which can affect the accuracy and stability of the simulation results.
There are several ways to improve the orthogonal quality of mesh on Ansys Workbench, such as:
- Using structured meshes, which have more regular and balanced cell shapes than unstructured meshes. Structured meshes can be generated by using the sweep or multizone methods in Ansys Meshing ¹².
- Using inflation layers, which create smooth transitions from the boundary layer to the core mesh. Inflation layers can be applied to the geometry or to the mesh, depending on the mesh method used ³.
- Using mesh controls, such as face sizing, edge sizing, body sizing, sphere of influence, etc. to refine or coarsen the mesh in specific regions or features. Mesh controls can help capture the curvature and details of the geometry and reduce the faceting angles ⁴.
- Using mesh quality metrics, such as skewness, aspect ratio, smoothness, etc. to evaluate and improve the shape and orientation of the mesh cells. Mesh quality metrics can be accessed from the mesh tab or the statistics tab in Ansys Meshing ⁵.

💥💥💥 How to create multi zones for meshing in Ansys Fluent ?
Ansys Fluent is a powerful computational fluid dynamics (CFD) software that can simulate various fluid phenomena such as turbulence, heat transfer, multiphase flow, and more. One of the features of Ansys Fluent is the ability to create different types of zones for different regions of interest in a geometry. Zones are collections of cells that share the same properties and boundary conditions. You can use zones to simplify the meshing process and reduce the computational cost.
There are different ways to create multi zones for meshing in Ansys Fluent, depending on your geometry and your objectives. Here are some possible methods:
- **Using the Zone Type Manager**: This method allows you to create multiple types of zones from a single geometry, such as solid, fluid, or mixed. You can then assign different properties and boundary conditions to each zone type. To use this method, you need to open the Zone Type Manager from the Meshing menu or by clicking on the Zone Type icon in the toolbar. Then you can select the zone type in the Multiple Types list and choose two or more zones in the Zones of Type list. You can also edit or delete existing zone types from this window³.
- **Using Cell Zone Separation**: This method allows you to separate a single cell zone into multiple zones by using different criteria, such as region name, region number, region type, or region size. You can then assign different properties and boundary conditions to each zone separately. To use this method, you need to open the Cell Zone Separation dialog box from the Meshing menu or by clicking on the Cell Zone Separation icon in the toolbar. Then you can select a cell zone and choose one or more criteria from the Criteria list. You can also edit or delete existing cell zones from this dialog box³.
- **Using Multiblock Meshing**: This method allows you to create multiple cell zones by generating a multiblock mesh that consists of several submeshes connected by faces or edges. You can then allocate different fluids to each submesh and assign different properties and boundary conditions accordingly. To use this method, you need to open the Multiblock Mesh dialog box from the Meshing menu or by clicking on the Multiblock Mesh icon in the toolbar. Then you can select a multiblock mesh option from the Options list and specify one or more submeshes from the Submeshes list³.
- **Using Watertight Geometry Workflow**: This method allows you to create multiple fluid regions with interfaces between them using a watertight geometry workflow that preserves continuity across boundaries. You can then apply share topology options to merge adjacent regions into one cell zone with shared properties and boundary conditions². To use this method, you need to open the Watertight Geometry Workflow dialog box from the Meshing menu or by clicking on the Watertight Geometry Workflow icon in
the toolbar. Then you can select a watertight geometry workflow option from
the Options list and specify one or more regions with interfaces from
the Regions list².

What are the advantages of using multi zones?
Using multi zones in Ansys Fluent can have several advantages, depending on your geometry and your objectives. Some of the possible benefits are:
- **Improved mesh quality**: Multi zones can reduce the cell count significantly by creating more efficient and structured meshes that cover the regions of interest. This can improve the accuracy and stability of the simulation⁴.
- **User control**: Multi zones allow you to create different types of zones for different regions, such as solid, fluid, or mixed. You can then assign different properties and boundary conditions to each zone type, such as density, viscosity, pressure, temperature, etc. This gives you more flexibility and control over the simulation³.
- **Boundary condition flexibility**: Multi zones enable you to impose boundary conditions on different regions using different methods, such as wall, inlet/outlet, surface, or volume. You can also use multiple fluid-solid interfaces or multiple fluid-fluid interfaces to model complex flow scenarios².
- **Rendering choices**: Multi zones can provide more choices for rendering the mesh and the flow-field solution by allowing you to select different surfaces for display. You can also use multiblock meshing or watertight geometry workflow to create multiple cell zones with interfaces between them¹.

Can you explain more about watertight geometry workflow?
Sure, I'll be happy to explain more about the watertight geometry workflow in Ansys Fluent. The watertight geometry workflow is a method to create a mesh that is CFD-ready in minutes. It is an intuitive guided workflow that streamlines the whole end-to-end process of importing a watertight or clean CAD geometry, creating a surface mesh, describing the geometry and extracting fluid regions, and generating a complete volume mesh³.
The watertight geometry workflow has several advantages over other methods of meshing, such as:
- It is easy to use and does not require any advanced skills or experience.
- It can handle complex geometries with multiple solids, interfaces, and boundaries.
- It can create high-quality meshes with minimal user intervention and maximum automation.
- It can save time and resources by reducing the number of manual steps and iterations.
The watertight geometry workflow consists of the following steps:
- **Import CAD geometry**: You can import your CAD model into Ansys Fluent using various formats, such as STEP, IGES, STL, etc. You can also use native Fluent files (.pmdb) that are created by Fluent when you import your model for the first time.
- **Create local sizing**: You can optionally add local sizing to your model to control the size of each cell zone. This can help you optimize the mesh quality and reduce the computational cost.
- **Create surface mesh**: You can create a surface mesh for your model using different algorithms, such as adaptive mesh refinement (AMR), multiblock meshing (MBM), or multiblock volume meshing (MBVM). These algorithms can improve the accuracy and stability of the simulation by creating more efficient and structured meshes.
- **Describe geometry**: You can describe your geometry using different tools, such as symmetry planes, symmetry groups, or symmetry operators. These tools can help you identify and define regions of interest in your model that have special properties or boundary conditions.
- **Extract fluid regions**: You can extract fluid regions from your model using different methods, such as capping tools, fluid-solid interfaces (FSI), or fluid-fluid interfaces (FFI). These methods can help you model complex flow scenarios where there are multiple fluids or solid bodies involved.
- **Generate volume mesh**: You can generate a volume mesh for your model using different options, such as automatic volume generation (AVG), manual volume generation (MVG), or hybrid volume generation (HVG). These options can help you create a complete CFD-ready mesh that covers all regions of interest in your model.

What is the difference between FreeCAD and OpenSCAD?
FreeCAD and OpenSCAD are both open source CAD software, but they have very different approaches to 3D modelling. FreeCAD is a parametric 3D modeler that uses a sketch-based approach, while OpenSCAD is a script-based modeler that uses a programming language. Here are some of the main differences between them:
- User interface: FreeCAD has a graphical user interface that resembles other commercial CAD software, such as SolidWorks or AutoCAD. It has various workbenches that provide different tools and functions for different tasks, such as Part Design, Draft, Mesh, FEM, etc. OpenSCAD has a non-traditional user interface that consists of a text editor and a 3D preview window. The user has to write code in a custom language to create and modify 3D models, and the preview window only shows the result of the code ¹².
- Modelling method: FreeCAD uses a parametric modelling method, which means that the user can create and edit 3D models by defining sketches, constraints, features, and parameters. The user can also modify the model history and change the parameters at any time. OpenSCAD uses a constructive solid geometry (CSG) method, which means that the user can create and edit 3D models by combining primitive shapes, such as cubes, spheres, cylinders, etc., using boolean operations, such as union, difference, and intersection. The user can also use variables, functions, and loops to create complex shapes ¹².
- Modelling flexibility: FreeCAD offers more modelling flexibility than OpenSCAD, as it supports various types of modelling, such as mechanical engineering, architecture, product design, and 3D printing. It also supports various types of meshes, solvers, and file formats. OpenSCAD is more limited in its modelling capabilities, as it only supports solid modelling and does not support meshes, solvers, or file formats other than STL, DXF, and SVG ¹².
- Modelling precision: OpenSCAD offers more modelling precision than FreeCAD, as it allows the user to define the exact dimensions and coordinates of the shapes using code. It also allows the user to use algorithms and mathematical expressions to create complex and accurate shapes. FreeCAD relies more on the user's graphical input and mouse movements, which can introduce errors and inaccuracies. It also has some issues with rounding errors and tolerance settings ¹².
- Learning curve: FreeCAD has a steeper learning curve than OpenSCAD, as it has a complex and crowded user interface, a large number of tools and functions, and a different workflow for each workbench. The user has to learn how to use the sketcher, the constraints, the features, and the parameters, as well as how to switch between workbenches and modes. OpenSCAD has a simpler and more consistent user interface, a smaller number of tools and functions, and a single workflow for all models. The user only has to learn how to write code in the OpenSCAD language, which is similar to C or Python ¹².
These are some of the main differences between FreeCAD and OpenSCAD, but there are also some similarities and advantages that they share. For example, they are both free and open source, which means that they are constantly updated and improved by the community. They also both have a large and active user base, which means that they have a lot of documentation, tutorials, forums, and support available. They also both have a modular and extensible architecture, which means that they can be customized and enhanced by adding plugins, modules, libraries, and scripts ¹²³⁴..

Can I simplify my mesh instead of geometry?
Yes, you can simplify your mesh instead of geometry, but it depends on the type and quality of the mesh that you want to use for your analysis. Generally, there are two types of meshes that you can use in FEA: hexahedral (brick) meshes and tetrahedral (tet) meshes. Hex meshes are more accurate and efficient, but they require more geometry preparation and are not suitable for complex shapes. Tet meshes are more flexible and can handle any geometry, but they are less accurate and require more elements and higher order elements to achieve the same accuracy as hex meshes³.
To simplify your mesh, you can use different meshing methods and parameters in Ansys DesignModeler or Ansys Mechanical. For example, you can use the Multizone method, which is a hybrid of hex and tet elements that allows you to mesh different parts of the geometry with different methods. This allows you to perform less geometry preparation and have more local control over the meshes³. You can also use the Meshing Toolbox in Ansys Mechanical to refine, smooth, or inflate your mesh according to your needs.
However, simplifying your mesh alone may not be enough to improve your FEA model. You should also consider the boundary conditions, the material properties, and the physics of the problem that you are trying to solve. Simplifying your mesh may reduce the computational cost and time, but it may also introduce errors or inaccuracies in your results. Therefore, you should always check the quality of your mesh and verify your results with analytical solutions or experimental data. You can find more information and examples on how to simplify your mesh in Ansys DesignModeler or Ansys Mechanical by following the links in the web search results. I hope this helps you to improve your FEA model. 😊.

Can I use other software for simplify geometry instead of Ansys Design Modeler or SpaceClaim ?
Yes, you can use other software for simplifying geometry instead of Ansys Design Modeler or SpaceClaim, as long as they are compatible with the file formats that Ansys supports. For example, you can use Geometry Calculator¹ or Desmos² to create and simplify 2D geometries, or you can use Geoprocessing Online³ or CoreTechnologie⁴ to simplify 3D geometries. However, you should be aware that different software may have different algorithms and parameters for simplifying geometry, and they may not preserve the topology or the accuracy of the original geometry. Therefore, you should always check the quality of the simplified geometry and compare it with the original geometry before importing it to Ansys. You can find more information and examples on how to use other software for simplifying geometry by following the links in the web search results. I hope this helps you to improve your FEA model. 😊.

💥💥💥 How to prepare proper mesh for structural analysis in Ansys Workbench ?
To prepare a proper mesh for structural analysis in Ansys Workbench, you need to follow some steps and consider some factors. Here are some tips and resources that might help you:
- Before you start meshing, you need to upload your CAD model or geometry into Ansys Mechanical and decide what features need to be meshed and what features can be defeatured. Defeaturing means removing unnecessary details from your geometry to save time and simplify the meshing process. For example, you can use Ansys SpaceClaim to defeature a name plate on your geometry if it is not relevant for your analysis 1.
- You also need to choose the type of mesh you want to create: structured or unstructured. Structured meshes have regular shapes and patterns, while unstructured meshes have irregular shapes and sizes. Structured meshes are usually more efficient and accurate, but they are harder to generate for complex geometries. Unstructured meshes are more flexible and easy to generate, but they may require more elements and computational resources 1.
- To create a structured mesh in Ansys Meshing, you can use various methods such as sweep, multizone, hex-dominant, or mapped face meshing. These methods allow you to control the shape and size of the elements along the geometry. You can also use inflation layers to refine the mesh near the boundaries where gradients are high 2.
- To create an unstructured mesh in Ansys Meshing, you can use methods such as tetrahedral, hexahedral, or polyhedral meshing. These methods allow you to fill the volume of the geometry with different types of elements. You can also use sizing controls to adjust the element size based on various criteria such as curvature, proximity, or relevance 1.
- To ensure the quality of your mesh, you need to check some parameters such as aspect ratio, skewness, orthogonality, smoothness, and Jacobian. These parameters indicate how well the elements represent the geometry and how suitable they are for the solver. You can use Ansys Meshing tools such as statistics, histogram, or mesh metrics to evaluate these parameters and identify any problematic areas in your mesh 1.
- To perform a transient structural analysis in Ansys Mechanical, you need to define the material properties, boundary conditions, loads, and time steps for your model. You also need to select the appropriate solver settings and options for your analysis type and goals. You can use Ansys Mechanical tools such as solution information, convergence plots, or result tracking to monitor the progress and accuracy of your solution 3.
The difference between structured and unstructured mesh is mainly in the way the elements are connected and arranged in the mesh. A structured mesh is a regular lattice, such as an array, with implied connectivity between elements. A structured mesh has orthogonal quadrilateral (2D) or hexahedral (3D) elements that are easy to identify and access. A structured mesh is more efficient and accurate, but it is harder to generate for complex geometries 1.
An unstructured mesh is a mesh with general connectivity (GCON) whose structure is arbitrary and therefore the connectivity of elements must be defined and stored. An unstructured mesh has non-orthogonal elements, such as triangles (2D) and tetrahedra (3D), that are more flexible and can conform to any desired geometry. An unstructured mesh is more easy to generate, but it may require more elements and computational resources 2.
I hope this answer helps you understand the difference between structured and unstructured mesh. If you want to learn more about the types of mesh and how to use them in Ansys Workbench, you can check out these resources:

Structured meshes are meshes with a regular and structured arrangement of cells, which are typically quadrilaterals or hexahedra in two and three dimensions, respectively. The sides of the cells are usually parallel, and the grid spacing is uniform. Structured meshes have the following advantages and disadvantages 1:
- Advantages:
- They are easier to generate, as the grid cells have a regular and structured arrangement that can be generated automatically.
- They are faster to solve, as the computation of the finite element solution can be simplified.
- They are more accurate in simple geometries, where the regularity of the mesh can help to reduce errors caused by distorted cells.
- They have lower computational cost, due to the regularity of the mesh.
- Disadvantages:
- They have limited flexibility, as the regularity of the mesh can limit its ability to conform to complex geometries or regions with curved boundaries.
- They have increased computational cost in regions where the solution is smooth, as the uniform spacing of nodes in structured meshes can lead to an excessive number of nodes in those regions.
- They are less accurate with complex geometries, as the regularity of the mesh may not be able to conform to the shape of the domain.
- Advantages:
Unstructured meshes are meshes with an irregular arrangement of grid cells, which can be any shape and size. The cells can be quadrilaterals and triangles in two dimensions, hexahedra and tetrahedra in three dimensions, and the grid spacing is not uniform. Unstructured meshes have the following advantages and disadvantages 1:
- Advantages:
- They are more flexible, as they can conform to any desired geometry with localized resolutions.
- They can handle complex geometries more easily, as they can fill the volume of the geometry with different types of elements.
- They can have arbitrary positions, as they do not depend on a predefined grid structure.
- Disadvantages:
- They require more memory, as they need to store more information about the connectivity and coordinates of each node and element.
- They are slower to solve, as they require more complex algorithms and computations to solve the finite element equations.
- They may have lower accuracy, as they may have distorted or poorly shaped elements that can affect the quality of the solution.
- Advantages:

What is better? SpaceClaim or Design Modeler in Ansys ?
SpaceClaim is a 3D CAD modeling software that runs on Microsoft Windows and is developed by SpaceClaim Corporation, which was acquired by Ansys in 2014². SpaceClaim allows you to quickly create, edit, or modify imported geometry without the complexity associated with traditional CAD systems. You can use SpaceClaim for various purposes, such as design and concept modeling, reverse engineering, 3D printing, model preparation for simulation and manufacturing, and more⁴.
SpaceClaim uses direct modeling techniques that let you manipulate the geometry with simple gestures, such as pull, move, fill, and combine. You can also add constraints and parameters to your sketches and save them with a block recording function. SpaceClaim can import and export various file formats, such as STEP, IGES, STL, etc⁵. SpaceClaim is integrated with Ansys Simulation packages as a built-in 3D modeler².

What is better: Ansys SpaceClaim or Ansys Design Modeler?
There is no definitive answer to which tool is better, as it may depend on your preferences, needs, and use cases. However, I can provide you with some information and comparisons based on the web search results that I have found.
- ANSYS DesignModeler (DM) and ANSYS Discovery SpaceClaim (SC) are both 3D modeling tools that can be used for creating and modifying geometry for simulation purposes¹.
- DM and SC use different geometry modeling kernels: DM uses Parasolid, while SC uses ACIS². This means that moving data between DM and other tools that use Parasolid (such as SOLIDWORKS) is easier than moving data between SC and those tools, as there is no need for translation². However, SC can also import and export various file formats, such as STEP, IGES, STL, etc³.
- DM has a history tree that records the sequence of operations performed on the geometry, while SC does not have a history tree by default (although it can be enabled with an optional feature)². This means that DM allows you to easily modify the parameters and constraints of the geometry at any stage, while SC requires you to use the block recording function to save and replay the operations⁴.
- SC has a more intuitive and user-friendly interface than DM, as it uses direct modeling techniques that allow you to manipulate the geometry with simple gestures such as drag, pull, move, etc³. SC also has more advanced features such as repair, simplify, optimize, etc., that can help you prepare the geometry for simulation faster and easier³.
- Both DM and SC have their own advantages and disadvantages, and you may need to use both of them depending on the situation. For example, you may want to use DM for parametric design and optimization, and use SC for complex geometry creation and modification².
