Hi everyone,
I am trying to simulate the thermal expansion of a cubic model under Global temperature load.
My question is how to constraint the model so that expansion can be seen on EVERY surfaces? For some reasons Wildfire 4.0 requires not a point, not an edge but at least one surface to be fixed in order to run the analysis.
I tried placing another model underneath and defined the interface between two models as "contact" with infinite friction enabled. However the result was totally incorrect even though expansion did appear on all surfaces.
Any advices would be greatly appreciated!!
