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…

Finite element analysis with finite element method (FEM)
New chapter
Since the beginning of the year, I’ve had less time to post interesting things on this blog. This is because fatigue.pro has become a side job, as I now work full-time as a research associate…
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…
Merry Christmas
A few days ago I had a result that look like a kind of Christmas star. Because I tried a few more things in Mecway. And I think it is one of the best free…
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…
Wind turbine hub calculation in Ansys
Some will already know the wind turbine hub model, but now I have taken the time and remade the model in Ansys Mechanical. At the latest, the following animated image should bring back memories of…
