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…
Category: PrePoMax
Pre and Post-processor with a modern user interface for the Calculix FEM solver.
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…
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…
