prewiew mesh motion
 

Hi all.

When I activate the preview mesh motion, I see the mesh move but at each time step Fluent brings me back this issue:

Updating mesh to time 1.00000e-01 (step = 00001)... Note: zone-surface: cannot create surface from sliding interface zone.
Creating empty surface.

Creating empty surface.

Can be a problem for simulation?
