- I am having a set up of impeller which is enclosed in an enclosure & in boundary condition I have specified velocity inlet and pressure outlet. an impeller is rotating at 2920 RPM I want to check the total pressure drop at the inlet and outlet.
2 after running my study if I check the convergence in the inlet and outlet. it seems that the beginning result is stable but in the end, suddenly it becomes unstable.
- I have checked with increasing time steps for a simulation run but still, I got the same plot
