I am working on a complex geometry of a CT scanned bone which was meshed and has SOLID70 elements. I am attempting to undertake a steady state thermal analysis on the geometry, applying a temperature of 35c on the exterior nodes at the top and a temperature of 22c on all exterior and interior nodes at the bottom. When I try to solve, I get the following error after which APDL abruptly crashes.
*** WARNING *** SUPPRESSED MESSAGE CP = 10.547 TIME= xxxxxx
Node (number) on element (number) is unselected.
This error repeats hundreds of times, followed by ansys crashing.
Any help in diagnosing this issue or letting me know what the error means will be greatly appreciated.
My code can be seen below.
