It is done! My CalculiX result interface has been implemented in the latest version 2.122 of Fatlab (download link). You can find more information about my latest CalculiX interface development in my blog post “Wind turbine hub…

Flattening tube in PrePoMax
Have you ever tried to flatten an aluminium tube in a vice? It is stronger than expected. I even damaged the vice a bit with this action. Then I made a model in FreeCAD and…
Happy New Year 2024
Thanks to all for a crazy year 2023 and say hello to the new year 2024. May it be even more colorful and exciting than the FEM calculation of the numbers in FreeCAD. I reused…
Bicycle steel frame in Mecway
I was looking for a way to calculate beams for one of my own projects. As PrePoMax does not yet support beams, so I have started in FreeCAD. Beams worked reasonably well in FreeCAD, even…
Wind turbine hub also rotates in Calculix
Now I reused the full Hexaeder mesh (Hex20 & Wedge15 only) from Ansys in PrePoMax to make some comparisons. In my post “Wind turbine hub calculation in Ansys” you find more information of the mesh…
Moving load with Julia in PrePoMax
Some weeks ago I prepared a simulation of a wheel with moving load in Ansys. And I would like to calculate the improved Ansys mesh in PrePoMax as well. So I translated the mesh from…
I went into the mesh
A post from Diego Magela Lemos on LinkedIn got me. He used the great work from Prof. Christophe Geuzaine to create a mesh from a picture in Gmsh. I already used Gmsh before to convert…
A chain is only as strong as its weakest link
Some month ago I prepared a geometry from a rest of a bicycle chain in FreeCAD. I used only a caliper to measure the dimensions. Because I really wanted to test the nonlinear contact in…
Happy Easter
I have found an Easter egg in FreeCAD. And thanks to FEM workbench in FreeCAD, the egg is even colorful. It was not so easy to find, because who actually knows how an egg is…
Steel wheel in PrePoMax
Keep the wheels turning. A steel wheel with shell elements has been on my list for a long time. In the past, I always had only aluminum rims with solid elements in the simulation (see…
