Stationary wall in MRF

AGP · July 9, 2014, 13:09

I need to specify a stationary wall (in absolute frame of reference) right next to a rotating zone. I tried two different boundary conditions -
1) Set it as stationary wall
2) Set the wall as moving in absolute frame of reference with 0 velocity.

Both these simulations give me completely different solutions. So which one of these is right?

A stationary wall is wall defined wrt the adjacent cells. Hence to define a stationary wall in the absolute frame of reference, the wall should be defined as moving with zero velocity.

Correct
