Import inhomogenous temperature distributions

Post by Albrechtduerer »

Hi everyone,

is there a way to do structural thermal analysis with imported temperature models? (individual nodal temperatures as initial condition)
There are solutions in Ansys, but I did not find any option to do so in FREECAD.

Greatful for any answer

Thank you

Yes, but you will have to export the .inp file, edit it manually and run the analysis using standalone CalculiX solver. Then you can postprocess the results in FreeCAD (if you import the frd file).

Here's what you should add to the input file:

*INITIAL CONDITIONS, TYPE=TEMPERATURE
node1, temp1
node2, temp2
...

node can be either node number or node set name.

Here's the documentation for CalculiX solver used by FreeCAD FEM module: http://www.dhondt.de/ccx_2.19.pdf
