💥💥💥 What are capabilities in PrePoMAX ?

PrePoMAX is an open-source pre and post-processor for the Calculix FEM solver based on a modern user interface to speed up the FEM workflow1. It allows you to import, mesh, define and visualize FEM features using the Calculix solver. It supports various CAD formats, meshing methods, feature definitions and result formats2.


Some of the capabilities of PrePoMAX are:

If you want to learn more about PrePoMAX, you can visit their official website1 or watch some tutorial videos2. You can also download the latest versions of PrePoMAX, the sample models, the meshers and the solver from their download page3.

Can I use PrePoMAX for 2D analysis?

Yes, you can use PrePoMAX for 2D analysis. PrePoMAX supports various 2D finite element types, such as plane stress, plane strain, axisymmetric, and membrane elements1. You can also import 2D CAD geometry or mesh files and define the analysis features based on them1.

To perform a 2D analysis in PrePoMAX, you need to follow these steps2:

  • Create a new model and select a 2D model space and unit system.
  • Import or create a 2D geometry for the analysis.
  • Set the mesh parameters and generate a 2D mesh.
  • Define the material properties and assign them to the geometry or mesh.
  • Define the analysis step type and the output requests.
  • Define the constraints, interactions, initial conditions, boundary conditions, and loads for the analysis.
  • Run the analysis and view the results.

You can watch this video tutorial3 to see an example of a 2D analysis of heat transfer in a double-pane window using PrePoMAX.

What is Calculix FEM solver?

Calculix FEM solver is a free and open-source software that can perform linear and non-linear finite element analysis of various physical problems. It can handle static, dynamic, and thermal simulations, as well as eigenvalue and frequency analysis. It uses an input format similar to Abaqus, a commercial FEM software1.

Calculix FEM solver consists of two main components: CCX, which is the solver written by Guido Dhondt, and CGX, which is the pre- and post-processor written by Klaus Wittig. Both programs can be used independently or together, and they run on Unix platforms like Linux and Irix, as well as on MS-Windows1.

Calculix FEM solver can be used with various CAD and meshing tools, such as PrePoMAX, which is an open-source pre and post-processor for Calculix FEM solver based on a modern user interface2. You can also use external CAD interfaces to import geometry from different formats1.

If you want to learn more about Calculix FEM solver, you can visit their official website1 or watch some tutorial videos3. You can also download the latest versions of Calculix FEM solver, the sample models, the meshers and the solver from their download page.

What are difference between Calculix FEM solver and Ansys Mechanical ?

Calculix FEM solver and Ansys Mechanical are both software tools that can perform finite element analysis (FEA) of various physical problems. However, there are some differences between them in terms of features, capabilities, and costs.

Some of the main differences are:

These are some of the main differences between Calculix FEM solver and Ansys Mechanical. However, both software tools have their own strengths and weaknesses, and the choice of which one to use may depend on the specific problem, the available resources, and the user’s preference.
