How To ... ANSYS - Tutorials, Tips and Tricks

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

 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.

In today's post, we will deal with another error that may occur during the analysis. The error that is described below concerns Fluent and the wrong definition of user monitors that are displayed during simulation. These can be monitors concerning the average velocity in the domain volume, the values of the maximum temperatures of the solid domains, the average values of the heat transfer coefficient from the defined planes of the model, etc. Generally speaking, today's entry is about how to correctly define monitors and how to transfer them between subsequent analyzes. Example of "gui-domain-label" error in Fluent 

ANSYS Fluent is a powerful software for simulating fluid dynamics and heat transfer problems. It can handle complex geometries (models) by using different meshing methods and workflows. Meshing is the process of dividing the geometry into small elements that can be used for numerical calculations. Depending on the type and quality of the geometry, you may need to use different meshing tools and techniques. One of the meshing methods available in ANSYS Fluent is the Watertight Geometry Workflow. This workflow is suitable for clean and watertight geometries, which means that there are no gaps, overlaps, or errors in the geometry. The Watertight Geometry Workflow can automatically generate a high-quality mesh for complex geometries, such as aircraft, cars, or turbines. You can also customize the mesh settings and refine the mesh in specific regions. To learn more about the Watertight Geometry Workflow, you can watch this video or take this course .
