How to model walls corresponding to solid MRF zones?
When MRF modeling for solid zone is modeled for example cylinder. To bring the effect of rotation on fluid due to the same, the wall corresponding to fluid zone at same location should be modeled rotating wall with similar rpm else the rotational effect from solid to fluid zone is not transferred.
This holds good for conformal mesh. Where wall and wall shadow will be formed. The wall corresponding to fluid zone needs to be given rpm.
