Thanks to all for the year 2024 and say hello to the new year 2025. May it be even more colorful and exciting than the FEM calculation of the numbers in FreeCAD. I reused my…

CalculiX interface in Fatlab
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…
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…
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…
Wind turbine hub calculation in PrePoMax
I would like to calculate the finite element stress of a 5MW wind turbine hub for a fatigue calculation in Fatlab and I came across PrePoMax. PrePoMax is an open-source pre- and postprocessor for an…
The temperature is still rising!
Normally, I evaluate measured strain time series to calculate a stress range spectra or the damage. But today I evaluated the temperature rise with Julia (https://julialang.org/), because I wanted to know where we are at…
