Woah! These figures are awesome! There is a huge improvement between FreeCAD 0.17 and 0.19 versions....

One question, FreeCAD 0.18 is stable for windows?

Re: [SOLVED] - Problems when loading calculix frd file

BTW, interesting geometry. What is this used for? Hello Bernd, I am using a simple nonsymmetric tetraedron mesh for understanding all calculix outputs in *.dat and *.frd files when performing frequency analyses. I am also analizing and modifiying the meshing (elements and nodes) using linear algebr...

Hello, I have some problems when loading an .frd file in FreeCAD. I create a simple frequency simulation (free-free conditions). The mesh is done by netgen algorithm using first order tetrahedron elements (C3D4). In report view I check the following error: Traceback (most recent call last): File "C:...

Re: missing stress values Sxy, Syz, Szy

Hello! Be careful with the shear stresses. Sxy, Syz, Szy... Calculix .frd file contains stress components per node. Calculix .dat file contains stress components per element. But the order of them is different (different indexes...) ! This is discussed here... https://forum.freecadweb.org/viewtopic....
