Hi Momo,
I’ve checked the settings and numerics and the simulation itself are set to steady-state - currently trying to run the simulation with the “test_model6,_new_fan-A” mesh and see if I can make it work.
Regarding the time step settings the names are just random variable names and you can leave the time step to 1. If you use the steady-state time discretization just leave the time step as 1 which is one iteration if you like. Your outputs are not time steps, they’re just named that way. Keeping you up-to-date!
Cheers,
Jousef
