[solved] Can't run buckling analysis in 0.20

Hi,
previously, when I was trying to submit the analysis in 0.20, I was receiving "No CalculiX binary ccx" error each time:
https://forum.freecadweb.org/viewtopic.php?f=18&t=60951
Now in the newest weekly build there's no such issue but I can't run buckling analysis successfully and it happens on 2 different computers. There's no pop-up window with error message, just some red-colored output in the Report View:
- error.JPG (59.37 KiB) Viewed 2915 times
and FreeCAD hangs completely (I have to kill it with Task Manager).
I also tried running this type of analysis with "Solver CalculiX (new framework) and it completes but the results seem empty.

this is a totally different error not related to buckling at all. You would need to post the file to make us find the problem. But since it is a different problem make a new topic.

it seams this is a problem of the calculix binary and not inside FreeCAD. ccxtools and calculix new solver framework eventually use the same ccx binary. See this topic suggested links.

We should get rid of this. Would you report back if you succeeded with a alternate ccx binary? Which FreeCAD did you download?

this was only meant as confirmation about what Thomas wrote, with my local computer..
I used his file beullast_zylinder, started buckling and had the same messages as thomas...
also with "INTEL MKL ERROR: Das angegebene Modul wurde nicht gefunden. mkl_intel_thread.dll. "
and the message about Nodecount

I tried using ccx_PARDISO downloaded from the CalculiX's homepage (newest release), placed in FreeCAD's bin folder and selected in Preferences --> FEM --> CalculiX --> CalculIX binary but I got errors saying: "FEM: wrong ccx binary", "FEM: CalculiX binary ccx ... not found. Please set the CalculiX binary ccx path in FEM preferences tab CalculiX" and "CalculiX has not been run. The CalculiX binary search returned: False.".
To get the newest FreeCAD weekly build I downloaded this file:

This is not FreeCAD 0.20.0 final. You must use at least this version.
In your error message you also see that an outdated LibPack was used. This had some issues with third-party libraries like CCX and others.
-----------
FC 0.20.1 will come out this week and comes with massive fixes for FEM.
