smoothing problem
Hi everyone,
I am just beginner with Ansys-Fluent 12.1 Workbench. I need to move with a wing in a wind tunnel. There is a small deflection of the wing so I chose smoothing method, wrote UDF (define_cg_motion). It works, but the problem is:
Just the first layer of the mesh around the wing moves, the others does not move, so after few time steps occures a warning: negative cell volume detected.
I do not have any idea about that, would you be so kind to help me?
Thank you in advance,
