I have a case that runs perfectly fine as incompressible without temperature consideration with fanPressure BC. Results are sensible and everything is good.
Now I need the same with heat transfer from the walls. I took a hot room tutorial and basically tried to transfer BC and everything to my case. If I drop my fanPressure and have instead fixedValue on the outlet, everything works fine. With fanPressure, no matter how I try it, it goes already in the first step wrong. If I set it only in p and not in p_rgh then the rho_min gets close to zero. If I put fanPressure BC into p_rgh then rho_min becomes negative and rho_max 5 times as big as it should be. Basically my questions are: 1. Is it possible to set-up heat transfer calc with fanPressure BC? 2. Any hints on how-to put fanPressure into p or/and p_rgh? Appreciate your time. ![]() |

Hi Lapka,
I took the circuitBoardCooling tutorial and applied fanPressure in p. it works well. When I want to apply fan for outlet, I define pressureInletOutletVelocity for velocity inlet BC, but it does not work! Have you found any solution? Last edited by Farhad.hz; July 27, 2022 at 04:04. |
