How to perform remeshing for 3D boundary layer elements

  Hi,
  I am trying to perform an FSI simulation in Fluent. The problem that I am currently working on is that when the walls undergo large deformation, the boundary layer elements become distorted and the simulation stops because of the negative volume elements error. Is there any way to maintain a good quality of boundary layer elements other than adjusting the diffusion parameter?
  Thank you.

  You may want to change inflation parameters.
  Please check following videos

  If possible, you can remove inflation and use only tet or hex elements.
