moving mesh
 

I am looking for algorithm to implement moving mesh in 3 dimensions for internal incompressible flow moving boundary problem. CFX uses a approach for its moving grid option but i couldnt find it.

Specifically, the problem is as follows - The location of all boundary points is known apriori as function of time (user-defined). Before i could go to next timestep, the algorithm should alter/relocate all 'interior' mesh points accordingly. Local refinement of mesh is also not required between timesteps.

Thanks in advance

Re: moving mesh
 

CFX can handle this. Moving meshes are well documented in the manual. Search for "mesh deformation" and do the FSI tutorial ...
