[Solved] FEM problems

hi, I am trying to learn calculix. When I run a simple thermo calc on my (older) Xubuntu laptop, I get an error report when I press CCX_Results. With a delay I get an "Ubuntu 20.04 has experienced an internal error". However the calculix runs fine and the output seems to be correct. When I run the same file on my win10 laptop no errors occur. Any ideas? Many Thx!

It's been raised a few times that some of the Daily builds haven't worked for nearly two months, yours is from March 3rd. The fix went in on the 5th March see git commit f6863bd
So I'm assuming your Win10 build is more up-to-date hence error free.

Thx for your prompt reaction! I am new to Ubuntu (and freecad:-), how can I download/ install a specific version > March 5th? I believe I have added PPA to the repositories but I still struggle with the sudo apt .... commands. Many thx!!

If you want stability with that fix in it then I would say the AppImage 0.19.1 available at https://www.freecadweb.org/downloads.php

If you want to be fully up-to-date then the latest AppImage (file ends in Linux-Conda_glibc2.12-x86_64.AppImage) available at https://github.com/FreeCAD/FreeCAD-Bund ... kly-builds
Remember with an AppImage you have to make it executable by right-clicking the file and selecting Properties, click the Permissions tab and tick Allow executing file as program

Thx, solved!
