I am currently attempting to run a simulation in Fluent 2023R1 on a HPC.
It’s a 3D pressure based simulation where I have two fan models present. It seems that the propellers are momentum models and I cannot find a way around this. As a result – the simulation will not run when fans are present. I have tried to force the models to pressure based – but I still receive the same error. The following is the ANSYS output: “> /define/models/solver/density-based-explicit no No change. > /define/models/solver/density-based-implicit no No change. > /define/models/solver/pressure-based yes > /solve/initialize/hyb-initialization turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 10429708 cells Note: Settings to improve the robustness of pathline and particle tracking have been automatically enabled.
