Number of nodes limitation - Calculix error 201

[Jckcdt]

used ccx build:
ccx_2.15_pardiso_dynamic.dhondt.exe from http://www.dhondt.de/
running as FreeCAD's subprocess

mkl libs from conda

I pasted all files from http://www.dhondt.de/calculix_2.15_4win.zip to replace existing ones in FreeCAD_0.19.18567_x64_LP_12.1.2_PY3QT5-WinVS2015\bin (Conda version doesn't launch on my computer).

But i still get this error message :

Writing CalculiX input file completed.
Run CalculiX ...
C:\Users\be91872\Desktop\Sauvegarde\Programmes\FreeCAD_0.19.18567_x64_LP_12.1.2_PY3QT5-WinVS2015\Mod\Fem\femtools\ccxtools.py:959: RuntimeWarning: libshiboken: Overflow: Value 3221225477 exceeds limits of type [signed] "int" (4bytes).

Could you explain in more detail how you used ccx_2.15_pardiso_dynamic.dhondt.exe as FreeCAD's subprocess ? Thanks in advance

Conda version doesn't launch on my computer

This package FreeCAD_0.19.18567_x64_LP_12.1.2_PY3QT5-WinVS2015.7z contains already ccx_pardiso_dynamic.exe

But AFAICS some dlls are missing needed by ccx_pardiso_dynamic.exe

So please download these packages
https://anaconda.org/anaconda/mkl/2019. ... 81.tar.bz2
and
https://anaconda.org/anaconda/intel-ope ... 81.tar.bz2
and copy all dll files from both packages to FreeCAD's bin folder where ccx_pardiso_dynamic.exe can be found.

Thanks for the heads up.

(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)

I pasted all the dll files in the bin folder, renamed ccx_pardiso_dynamic.exe in ccx.exe and everything is working fine now.

Thanks a lot !

I also don't see this limitation with ccx from conda-forge. But there was another limitation: https://github.com/FreeCAD/FreeCAD/pull/2659

No idea why nobody else run into these issues.

What would be the extension of the log file in that folder ?

When I launch the Conda version, i just have the first loading screen, then nothing happens. But the LP version works fine now.

It's called FreeCAD.log

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

Hello there,

I am new to this forum and with me the same error 201 occurs. After calculation nodes of the mesh are highlighted (see pictures)

FEMFailError201_02.JPG (211.79 KiB) Viewed 4555 times

FEMFailError201_01.JPG (183.34 KiB) Viewed 4555 times

I tried to fidle with the mesh attributes, yet even with finer meshing the error keeps occuring.
Anybody got any hints for me?
@Jckcdt: Same problem or do You have a different outcome?

Cheers,

PJ

If you get these green marks it means you have nonpositve jacobians in your mesh. Check the report window. You should have lots of erros in this regard. There are various topics in the forum about nonpositve jacobians in teh mesh.

This is a totally different problem than the one of this topic. Just the retruned error code of CalculiX (201) is the same.

Try a smaller mesh size or try to mesh wih netgen.

Or clear the mesh and post the geometry.
