How to use movingWallVelocity the right way?
i have a question regarding the movingWallVelocity BC:
In my calculations i compare two different setups using the velocityLaplacian meshMotion solver:
A) Use the same dirichlet velocity BC at the moving wall as the velocity in my cellMotion U file (such that in my interpretation the relative velocity is zero).
B) Use the movingWallVelocity (0,0,0) BC and use the same cellMotion U velocity as in case A)
As i understand these pair of calculations should lead to the same result.
But as you can guess now they don't.
Do you have any suggestions?
thanks a lot
Recently I have the same confusion as you proposed. I'm wondering have you figured it out?
