I am simulating Battery pack in openfoam. The mention domain is meshed with tetrahedral mesh in salome. Mesh quality is checked through checkMesh utility and mesh is OK. (22 non-Ortho faces though.) So scheme used was limited linear 0.5. solver used is chtMultiRegionFoam (openFoam 9).But I am experience very slow increase in cell (sub-domain in battery) like 0.003 deg C in each iteration and even after 15000 iteration solution was not converged . But with Ansys fluent same problem was converged in hardly 300 iteration. And many time solution is also diverged after 10000 iteration. So my question are :
1. Is openFoam capable to simulate conjugate heat transfer in steady state?
2. Does courant number affect in steady state simulation? and how?as my domain is very complex so its obvious with very fine mesh my courant number will be high too.
3. Any reason behind extreme slow convergence of chtMultiRegionFoam for steady state CHT simuilation?
