CFD for moving bodies

Alan

Hello,

I am new to the field of simulating the flow around moving bodies. I have so far thought about using Chimera (overset grids) since it is a nice method.

However, I am also thinking of coupling a cfd solver with a mesher. The scenario would be something like: 1) Generate an unstructured mesh 2) Compute the flow and extract the forces acting on the body. 3) Move the body corresponding to an ODE or to a given trajektory 4) Remesh the domain and compute again the flow

Here are my questions: 1) Is this approach feasible? 2) Has anybody experiences with coupling a CFD solver with a mesher? I mean, the solver knows only the mesh. Yet, the mesher needs geomtries (like CAD surfaces) in order to do the meshing. Is there a method to go back from the CFD mesh to the CAD surfaces in order to feed the mesher with the new position of the body? Or are there any better approaches to coupling a CFD solver and a mesher?

Thank you very much for any hints, explanations, and infos.
