Hi,
I'm trying to solve a laminar flow natural convection case that close-packed geometry. The cylinder's wall adiabatic. The mesh generated with this steps:

Boundary conditions seem right to me but I know that if TSCE increases this is mostly related to BCs. I'm open to suggestions. Files are attached. Kind regards, Said. Last edited by saidc.; December 17, 2021 at 18:00. |

Update,
Instead of using the boussinesq approximation and other equationOfStates in thermophysicalProperties, I changed the solver to buoyantBoussinesqPimpleFoam and it runs smooth for now. Really interesting. But I don't think the results will be good because in this case the temperature difference is 100 K. Let's see what happens. I'll keep update. Kind regards, Said.
