I want to simulate the interaction between the rotating fan and the fluid domain. Axial-fan is rotated with 600 rad/s. The tan consists of the fixed shaft and wing(?) as multi-body assembly model. Under the constant rotating speed, I tried to implement the transient(time-dependant) analysis. But the solution was not converged. I want to ask how to fix this simulation model. COMSOL file was attached.
