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…
Tag: CalculiX
a free and open-source finite-element solver that uses an input format similar to Abaqus
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…
Wind turbine hub calculation in Fatlab (PrePoMax results)
Finally, the CalculiX interface in Fatlab now works also for more complex results from PrePoMax. The following video shows a complete fatigue calculation run of a simple hub in Fatlab with PrePoMax (Calculix) results. I…
FreeCAD FEM results in Fatlab
If you have a simple model and load you can directly use FreeCAD FEM workbench results in Fatlab. In the previous post I had introduced the newly implemented interface to use CalculiX results in Fatlab…
PrePoMax / CalculiX results in Fatlab
I show my first implementation of a model and unit stress interface for PrePoMax / CalculiX results in Fatlab. Now I am able to import the calculated FEM mesh model from the CalculiX ccx input…
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…
