hi, all,


I am doing the rotating propeller simulation recently. The simulation converges very slow, so I just do the post processing for the step of 600. I found a very strange phenomenon as shown in the figures below. The velocities of the two sides of interfaces are completely not the same. I wonder what could be the possible reason for such situation? Is it the reason of the mesh? I have checked the mesh in the tutorials, but I found nothing.


Thanks in advance.

Look at the variable "Velocity in Stationary Frame".
