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

on

 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! 😊

In Polish 

Błąd: GENERAL-CAR-CDR oznacza, że wystąpił problem z kodem Scheme w programie Ansys Fluent. Scheme to język programowania używany do pisania funkcji zdefiniowanych przez użytkownika (UDF) lub makr w Fluent 1. Błąd ten pojawia się, gdy Fluent oczekuje listy wartości, ale otrzymuje inną wartość, np. fałszywą (#f) 2.

Możliwe przyczyny tego błędu to:

  • Niepoprawna skÅ‚adnia lub brakujÄ…ce znaki w kodzie Scheme
  • Niezgodność typów danych lub argumentów w funkcjach Scheme
  • NieprawidÅ‚owe ustawienia lub opcje w Fluent

Możliwe rozwiązania tego błędu to:

  • Sprawdzenie i poprawienie kodu Scheme, upewniajÄ…c siÄ™, że wszystkie nawiasy i cudzysÅ‚owy sÄ… zamkniÄ™te i dopasowane
  • Sprawdzenie i poprawienie typów danych i argumentów w funkcjach Scheme, upewniajÄ…c siÄ™, że sÄ… zgodne z dokumentacjÄ… Fluent
  • Zapisanie i ponowne otwarcie pliku przypadku i danych
  • Zresetowanie zakÅ‚adki ustawieÅ„ Fluent i ponowne otwarcie siatki
  • Przemieszanie geometrii i ponowne otwarcie w 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
