How to... make 3D any variable distribution in Ansys postprocessing

on

A very interesting option in post-processing in Ansys is the generation of 3D distributions that can be easily done using the IsoSurfaces function. We can distribute any variable by defining ranges of values of different sizes. The entire graphic design of the generated distribution also depends on us. When it comes to IsoSurfaces, we have a very wide range of modular possibilities with this function.

The first step is to select the IsoSurfaces function in postprocessing. To do this, right-click on User Locations and Plots and select IsoSurfaces. The Details of IsoSurfaces window will appear in which we select the model element (Domains) where we plot our 3D distribution, the variable selection field and the range of values to be displayed. You can see these functions below (Geometry tab).

On the next tab (Render), we can precisely define the graphic properties of our 3D plots. Transparency function is very useful when we put several IsoSurfaces on each other because thanks to this option we can modulate the transparency of subsequent layers. As in the first picture in this post, we have superimposed several speed ranges on each other and using the Transparency function we are able to present all generated IsoSurfaces on one projection.

Other functions like Lighting (green frame) and Apply Texture (blue frame) are used for visual processing of our generated 3D layouts. Below you can see how these functions affect the visual appearance of IsoSurfaces.

The next View tab is especially helpful for generating images of complete models from geometries simplified by symmetry or linear / circular periodicity.

Defining the colors of our IsoSurfaces is also a very important function. We will perform this option in the Color tab. We can set a constant color of our 3D distribution or adjusted to the value ranges of our variable (Use Plot Variable). The solid color is extremely helpful for us when we are dealing with many layers of IsoSurfaces.

Below you can see the temperature distributions shown with IsoSurfaces from previous blog posts. Of course, we do not have to limit ourselves only to temperature or speed as our variable. In fact, the presentation of the results depends only on us because we have very wide possibilities offered in the Ansys software.

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  BÅ‚Ä…d: GENERAL-CAR-CDR oznacza, że wystÄ…piÅ‚ 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

💥💥💥 How to define a porous model in Ansys Fluent?

 Defining a porous model in Ansys Fluent involves specifying the region of your geometry that represents the porous media and assigning its properties. Here's a breakdown of the steps: **1. Defining the Porous Zone:** * In the Setup stage of Ansys Fluent, navigate to the **Cells** menu and choose **Zones**. * In the Zones window, click **Create** and select **Fluid**. This creates a new fluid zone. * Right-click on the newly created fluid zone and choose **Edit**. * In the Edit Fluid Zone window, locate the **Porous Zone** option and enable it. This activates the porous media functionalities for this zone. **2. Specifying Porous Media Properties:** * With the Porous Zone enabled, you'll see additional options appear in the Edit Fluid Zone window. Here's what you need to define:     * **Porosity:** This represents the volume fraction of the void space within the porous media. Enter a value between 0 (solid) and 1 (all void).     * **Momentum:** You can choose between differe
