Hello All

I am currently trying to model a plate moving along a specified path in order to measure lift and drag forces/coefficients as it moves. I am doing this using Ansys CFX and specifying a moving mesh of a cylindrical subdomain which contains the plate. I use the cylindrical subdomain so that the mesh within that domain does not deform, instead only mesh in the outer domain deforms where the flow is not significant.

My issue is in the outer domain, the mesh deformation very highly skewed element and eventually negative elements which causes the simulation to crash.

I would like to use a remeshing controller during the simulation to remesh the outer domain while leaving the inside domain as is however I can not find any good tutorials explain how to do this. I have a very little bit of experience with ICEM MESH so if i need to use that, that is okay but i'd much rather use the CFX meshing to do this.

If anyone has any experience with using a User Defined remesh parameter can you please help guide me on how to set this up or could anyone point towards some good tutorials explaining how to do this.

Thank You,

DM
