Altair has opensourced Radioss into OpenRadioss (Maybe we can add it as a FEM solver?)

Post by NewJoker »

Just to let you know, today Altair turned their advanced dynamic FEA code Radioss into open-source solution: https://www.openradioss.org/

That’s a potential revolution in open-source FEA software. Maybe this solver could be included in the FreeCAD FEM module in the future…

The only problem is that this code seems to be meant for Linux only but maybe it could be adapted for Windows as well.

Hello,

Thanks for this information. :)
I don't have much experience in Freecad but we need to have shell mesh if we want to run some crash analysis with Radioss.
Is it possible with Freecad to generate shell mesh ?

Yes, both meshers used by FreeCAD (Netgen and Gmsh) can generate shell meshes.

Anyone know how to do 'sh' under Windows?

Code: Select all

2>'sh' is not recognized as an internal or external command,
In its CMakeLists.txt,
'sh' is needed here:

Code: Select all

#include always rebuild 
add_custom_command(    
         OUTPUT 
            ${Build_includes_directory}/__foo.inc 
            ${Build_includes_directory}/build_info.inc
         COMMAND 
            sh ../../Compiling_tools/script/or_compile_info_cm.sh linux64 0 e 0 linux64  > ${Build_includes_directory}/build_info.inc
         )
What this 'sh' does? How I simulate it under Windows? Thanks.

I guess it run this 'or_compile_info_cm.sh' script to create a file named build_info.inc?
