Well, Please read the manual (theory) in each version, and try to realize that how displacement can be determined where the model is subjected to thermal loading. I can guess the solver is probably upgraded in new version.
Hi, alright. We now know the degree of geometry non-linearity is important. Well, I suggest you that review the [highlight #3465A4]solver[/highlight] in both version. Is that a big difference between results?
First of all, Abaqus might have a very good user interface,but the solver in coupled simulation is not generally as good as ANSYS.
Anyway, to those have a concern about "Creep Analysis"
Steady state (Secondary creep), the strain rate only depends on stress. Hence, You need A,n as...
