Re: 2D axisymmetric

Hello, Any chances to get it work on a 3D analysis on a complex geometry ? I'm trying to modelize the stresses in the welds between the hub and the flanges of a gear wheel of about 4 meters diameter, so the number of nodes if more than 5 millions, and Calculix goes outrange. As it is a axisymmetric ...

Hello,

Even if it's not related to the problem presented in the topic, I had to deal with this one too. For my experience, when you see these green dots, its in fact a matter of jacobian and mesh refinement.

Sorry, Windows searching engine doesn't find any Freecad.log on my computer
I looked by myself in the Appdata folder, there is no Freecad 0.19 folder, only 0.18

Re: Number of nodes limitation - Calculix error 201

(Conda version doesn't launch on my computer). Can you post any errors from "FreeCAD -l" from the command line? The log will be in %appdata%/FreeCAD (hidden directory) What would be the extension of the log file in that folder ? When I launch the Conda version, i just have the first loadi...

Conda version doesn't launch on my computer But AFAICS some dlls are missing needed by ccx_pardiso_dynamic.exe So please download these packages https://anaconda.org/anaconda/mkl/2019.5/download/win-64/mkl-2019.5-281.tar.bz2 and https://anaconda.org/anaconda/intel-openmp/2019.5/download/win-64/inte...

Re: Number of nodes limitation - Calculix error 201

Hello,

I tried the V0.19, but still have the same problem : Calculix crashing when I exceed 350.000 nodes :

Writing CalculiX input file completed.
Run CalculiX ...
OverflowError
CalculiX failed with exit code 3221225477

Do you have any idea where it comes from ?

Thanks

Number of nodes limitation - Calculix error 201

Hello, I have a recurrent problem using the FEM module of Freecad. As soon as GMSH creates more than about 350.000 nodes, I have a message error “Calculix error 201” during calculation. Do you know if/how it would be possible to exceed this number of nodes limitation? I am using Freecad version 0.18...
