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 for Windows on a HP Z440 workstation (Intel Xeon CPU E5-1650 v4 @y 3.60GHz,3601 MHz, 6 cores, 12 logical processor – 64Gb RAM)
Thanks in advance for your feedback,
Jonathan

Please always post you Help > About FreeCAD > Copy to clipboard
Per recommended guidelines for FEM, please test this in the FC development version 0.19.x
You can get it from https://github.com/FreeCAD/FreeCAD/rele ... g/0.19_pre

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

Re: Number of nodes limitation - Calculix error 201
I can confirm this for:
OS: Windows 10 (10.0)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.18524 (Git)
Build type: Release
Branch: master
Hash: bea009c1d52b97655dab2d5c0fbddec30989a902
Python version: 3.6.8
Qt version: 5.12.1
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: German/Switzerland (de_CH)
It is easy to test, just use 3D cantilever from start wb and make a fine mesh with 50 mm maximal element size.
which has ccx 2.15 preinstalled. But I do not know where this version comes from.
I will give it a try on Linux too. Next to try is if ccx gives the same error if run standalone with the inp file. Than it would be a ccx problem not a FreeCAD problem.
