Can I use PrePoMAX for fluid dynamics simulations?
PrePoMAX is mainly designed for structural mechanics and heat transfer simulations, but it can also be used for fluid dynamics simulations in some cases. According to the PrePoMAX manual², you can use PrePoMAX to set up a steady state dynamic analysis or an explicit/implicit dynamic analysis with fluid elements. However, you need to have some knowledge of the Calculix solver and the input file syntax to perform these types of analysis. PrePoMAX does not provide a graphical interface for defining fluid properties, boundary conditions and loads for fluid elements. You need to edit the input file manually or use a text editor to add these definitions. PrePoMAX can only visualize the results of fluid dynamics simulations using 2D plots, not 3D scalar fields. Therefore, PrePoMAX is not the most suitable software for fluid dynamics simulations, but it can be used as a tool to create and modify the mesh and the input file for the Calculix solver.

What is the difference between PrePoMAX and Calculix?
PrePoMAX and Calculix are two different but related software for finite element analysis. The main difference between them is that PrePoMAX is a pre and post-processor, while Calculix is a solver. This means that PrePoMAX is used to create, modify and visualize the FEM models, while Calculix is used to perform the actual calculations and simulations. PrePoMAX is based on a modern user interface that allows you to import, mesh, define and visualize FEM features using the Calculix solver¹. Calculix is a command-line based program that requires an input file with the FEM definitions and parameters². PrePoMAX can generate and edit the input file for Calculix, as well as display the results in 3D scalar fields or 2D plots¹². PrePoMAX and Calculix are both open-source software that you can download and modify for free¹²³. PrePoMAX is developed by Dr. Matej Borovinsek from the University of Maribor in Slovenia, while Calculix is developed by Guido Dhondt and Klaus Wittig from Germany¹². PrePoMAX and Calculix are compatible with each other and can be used together to perform various types of simulations, such as structural mechanics, heat transfer, fluid dynamics and more¹²³.

What are the limitations of PrePoMAX?
PrePoMAX is a great software for finite element analysis, but it also has some limitations that you should be aware of. Some of the limitations of PrePoMAX are:
- PrePoMAX is mainly designed for structural mechanics and heat transfer simulations, but it can also be used for fluid dynamics simulations in some cases. However, you need to have some knowledge of the Calculix solver and the input file syntax to perform these types of analysis. PrePoMAX does not provide a graphical interface for defining fluid properties, boundary conditions and loads for fluid elements. You need to edit the input file manually or use a text editor to add these definitions. PrePoMAX can only visualize the results of fluid dynamics simulations using 2D plots, not 3D scalar fields¹.
- PrePoMAX does not support nonlinear material models, such as plasticity, creep, damage and hyperelasticity. You need to use Calculix directly or another pre and post-processor to perform simulations with these material models².
- PrePoMAX does not support contact interactions between different parts or surfaces. You need to use Calculix directly or another pre and post-processor to perform simulations with contact interactions².
- PrePoMAX does not support parallel processing or distributed computing. You need to use Calculix directly or another solver to perform simulations with multiple processors or clusters².
- PrePoMAX is still under development and may have some bugs or errors. You need to check the validity and accuracy of your results and report any issues or feedback to the developers².
