In the temperature distribution at 15:40, the two mesh layers in the middle seem to stay at the initial temp of 20 degrees, does this mean that the result is not at a steady state? If so, how to compute the steady state, and why is it different from pure mechanical problems where steady state is achieved at step 1?
I figured that out myself. In static, general step no heat transfer process is computed so the temperature always stays the same as you set it. One way to perform a steady-state thermal-mechanical simulation is to first compute a temperature field in a heat transfer step, then use the .odb output file, which includes the steady-state temperature result, as a temperature load in a static, general step. Yet this approach only applies when the problem can be decoupled. Otherwise the coupled step should be adopted.
you're the best bro, I want to model a special material, known as shape memory polymers, and I found that almost papers published are used USER MATERIALS SYBROUTINES, (UMAT), How can I get your MAIL to ask you about that ?? Thanks in advance.
