Force report in CYLINDRICAL coordinates
 

Hello all!

I am running a rotating machine with a periodic boundary condition set. The rotating part as some kind of columns, so to say, and I want to have the forces exerted on them.

I can export the forces in a certain direction, but the mesh is moving, and because of the periodic boundary is quite confusing to get the proper angle (plus, I can get the centroid, but not the accurate position of each face).

The optimal option would be to get the forces in radial and tangential directions, but I have no idea about how that can be done.

Any input would be great.

Thanks!
