I have a model which I ran in three different COMSOL versions and results are different. I haven't changed anything.
Does someone has anyidea what global setting changed between the 4.3b, 5.0 and 5.4 versions or how to get the same results by disable the said settings?
Good afternoon, Noman Iqbal!
Unfortunately, we also encountered such a problem in this program when simulating the temperature distribution from one-sided heating of refractory elements (Сomsol 5.0). After checking in Сomsol 5.4, the results were different, in order to understand what the reason was, it was written to the developers. To which they gave a short answer ... That there were no significant changes to the program, some problems with the transformation of the voxel structure were eliminated. To date, no new comments have been received. We will keep you informed.!
Thank you Rostislav Podolskyi .
My problem is also similar ~ temperature-dependent deformations solved through coupling the PDE and solid mechanics modules. To my understandings previously the calculations were done on a fixed frame and then moved to a deformed one. Three versions give different results that's quite interesting.
I couldn't find any direct settings to enable/disable to get similar results.
Not that much. The boundary conditions and initial state conditions are the same for all solved PDEs and geometry structure.
Sorry M Saleh Sanjari Nia I am not asking about the specific model settings (BCs and ICs are the specific settings defined for each model). I am asking for general settings of the COMSOL modules.
