Default what does sliding mesh REALLY mean?
Posts: n/a
I am really confused by sliding mesh. Does the velocity of sliding mesh mean the velocity of each fluid element in that mesh? In another word, if one part of mesh is sliding at velocity V, is the fluid in that mesh also moving at velocity V? Could it be used for steady flow or only for unsteady flow?

The velocity u r specifying is the velocity of the object which is moving ( either translational or rotational). That does not mean the velocity of the mesh or the fluid particles. Sliding mesh is used only for Time dependent Solutions where Mesh generation at each time step is required.
