Hello, I would like to mode

Hello,

I would like to model a free falling wedge in water. Something like that: http://www.cfd-online.com/OpenFOAM_D...ges/1/5836.jpg.

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

I haven't tried it but i believe you should look into icoDyFoam
