πŸ’₯πŸ’₯πŸ’₯ PrePOMAX vs Ansys Mechanical

on

 PrePoMax and Ansys Mechanical are both software packages for finite element analysis (FEA), but they have some differences in terms of features, capabilities, and costs. Here are some points of comparison:

- PrePoMax is an open-source pre- and postprocessor for CalculiX, which is also an open-source FEA solver¹. Ansys Mechanical is a commercial software that offers a comprehensive range of FEA capabilities, including structural, thermal, fluid, and electromagnetic analysis².

- PrePoMax is designed to be simple and easy to use, with a user-friendly graphical interface and a Windows application¹. Ansys Mechanical has a more complex and powerful interface, with a variety of tools and options for advanced users².

- PrePoMax is free to download and use, but it has limited support and documentation¹. Ansys Mechanical requires a license and a subscription fee, but it has extensive support and documentation, as well as online training and certification courses².

- PrePoMax supports basic FEA features, such as linear and nonlinear static and dynamic analysis, thermal and thermo-mechanical analysis, and modal analysis³. Ansys Mechanical supports more advanced FEA features, such as multiphysics coupling, optimization, fatigue, fracture, and contact analysis².

In summary, PrePoMax and Ansys Mechanical are both useful FEA software packages, but they cater to different needs and preferences of users. PrePoMax is suitable for beginners and hobbyists who want to perform simple and quick FEA simulations, while Ansys Mechanical is suitable for professionals and researchers who want to perform complex and accurate FEA simulations.

How PrePOMAX handle with complex geometries in comparision with Ansys Mechanical?

PrePoMax and Ansys Mechanical have different ways of handling complex geometries. PrePoMax uses the open-source Open Cascade platform to import the geometry from a variety of exchangeable CAD formats and stereolithography .stl files used for 3D printing¹. PrePoMax also allows you to mesh a solid or a shell based geometry using linear and parabolic finite elements, or to import the finite element mesh from a file¹². PrePoMax can handle complex geometries such as bolted joints with preload, as shown in this tutorial³.

Ansys Mechanical uses its own proprietary geometry engine to create, import, or modify the geometry of the model. Ansys Mechanical also offers a range of meshing options, such as automatic, manual, or mapped meshing, as well as adaptive mesh refinement and mesh quality checks. Ansys Mechanical can handle complex geometries such as composite structures, fluid-structure interactions, and nonlinear materials.

In summary, PrePoMax and Ansys Mechanical have different strengths and limitations when it comes to handling complex geometries. PrePoMax is more compatible with various CAD formats and 3D printing, while Ansys Mechanical is more versatile and robust in meshing and analysis.

Can PrePOMAX handle fluid-structure interactions?

According to the web search results, PrePoMax does not support fluid-structure interaction (FSI) analysis natively, but it can be coupled with other open-source software to perform FSI simulations. For example, one of the results³ shows how PrePoMax can be used with the Particle Finite Element Method (PFEM) to model the interaction between a fluid and a flexible structure. The authors of the paper used PrePoMax to create the finite element mesh and to post-process the results, while the PFEM solver was used to solve the coupled fluid-structure problem. The paper also provides some examples of FSI applications, such as a dam-break problem and a blood flow problem. Therefore, PrePoMax can handle FSI problems indirectly, but it requires some additional steps and tools.

How can I install PrePOMAX on my computer?

To install PrePOMAX on your computer, you can follow these steps:

- Download the latest version of PrePOMAX from the official website¹. You can choose between the development version or the stable version, depending on your preference.

- Extract the downloaded .zip file to a non-system directory of your choice. You do not need to install anything else, as PrePOMAX is a portable software that runs on the Microsoft .NET Framework 4.8¹.

- Run the executable .exe file named PrePoMax v#.#.#.exe, where #.#.# is the version number. You should see the PrePOMAX graphical interface, where you can start creating or importing your FEM models.

That's it! You have successfully installed PrePOMAX on your computer. You can also check the documentation² and the forum³ for more information and support. I hope you enjoy using PrePOMAX for your FEM simulations. 😊

How to... use GPU on Ansys Fluent

 In an earlier post, I presented how to configure CAE calculations using the GPU in Ansys Mechanical. Today I would like to show you how to configure the use of a graphics card in Ansys Fluent. First of all, you need to correctly configure the proportion of the use of the amount of CPU to GPU depending on the HPC license you have. How to properly use GPU in Ansys Fluent

Quick Tip: How to fix Error: GENERAL-CAR-CDR in Ansys (Fluent)

 The error message Error: GENERAL-CAR-CDR: invalid argument [1]: improper list means that there is a problem with the scheme code or the UDF (user-defined function) in your case or data file . Some possible solutions are: Save the case and data file and try to reopen it. Reset the Fluent Setup tab and try opening the mesh. Remesh the geometry and reopen in Fluent. Change the material definition from “Solid” to “Fluid” in Design Modeler. Change the transient to steady if you are using evaporation-condensation as the phase interaction mechanism. Check the syntax of your UDF and make sure it follows the new rules in Fluent 6.2.16 or later. I hope this helps you resolve the error. If you need more assistance, please visit the Ansys Learning Forum or contact Ansys Support . Have a nice day! 😊 Sources: 1. smartadm.ru 2. cfd-online.com 3. forum.ansys.com 4. forum.ansys.com In Polish  BΕ‚Δ…d: GENERAL-CAR-CDR oznacza, ΕΌe wystΔ…piΕ‚ problem z kodem Scheme w programie Ansys Fluent.

Types of supports and examples - Ansys Static Structural

Supports are used to represent parts that are not present in the model but are interacting with it. Supports help truncate the domain, which helps in efficiently obtaining numerically accurate results without modeling parts of the geometry that are not of primary interest. There are different types of support available, among which you need to choose the appropriate one for your analysis. Here are some of the common types of supports and their explanations: - **Fixed Support**: This type of support constrains all the degrees of freedom of the selected entity (body, face, or edge). It means that the entity cannot move or rotate in any direction. Fixed support is equivalent to applying zero displacement to all directions. Fixed support is useful for modeling rigid connections or supports that do not allow any movement. For example, you can use fixed support to model a bolted joint or a clamped beam. - **Displacement Support**: This type of support specifies a zero or non-zero displacemen
