Something like that: . I'd like to solve it using mesh motion (but no deformation): the mesh is moving but its topology and relative position are fixed. In this 2D case, i have 3DOFs. (X,Y, rotation around Z). So the solving process would be: 1) time t 2) solve flow 3) compute forces 4) 'move' mesh (move=translate and rotate) solving the equation of motion. 5) update boundaries 6) go to time t+dt So my first question is: does this look OK and feasible? My second question is about the implementation: Looking through the forum and trying a few things, I would use rasInterFoam as basis of the flow solver. Moving the mesh seems also ok (mesh.move();.....). But i am struggling at point 5. In the main I will solve for the mesh velocities (after getting the forces); (here U,V and omega). How can I send (in a nice way) these values to the boundaries?. Regards, Nicolas
