Hi everyone,

I have been trying to run some simulations moving the whole mesh as a rigid body using pimpleDyMFoam as starting point. I can run simple oscillating cases in pimpleDyMFoam and the results agree with the analytical values (i.e. Theodorsen function for an oscillating airfoil).

I want to move now to rhoCentralDyMFoam, as I have been working with it for a while already. If I deform the mesh, I get similar results to what I was getting in pimpleDyMFoam. However, when I try to move the mesh as a rigid body, rhoCentralDyMFoam still asks for a solver, and even if I provide one I think it is mixing the two approaches.

Taking a look at rhoCentralDyMFoam.c I have seen that it calls motionSolver.H and CreateMesh.H, instead of dynamicFvMesh.H and CreateDynamicFvMesh.H. So, it seems that when it was programmed it was not intended to use all the capabilities available in some other solvers.

Can anybody put some light into this?. I have started to modify the code to make it work with solid body motions, but maybe there was a good reason not to do this at the original time and I might just be wasting my time...

Thanks a lot and best regards
