Hey guys,
So I pretty much fumbled upon OpenFOAM 6 months ago and have been using it a lot these days. I am trying to simulate a unique problem which requires a moving mesh and a sixDoF solver.

Consider it to be a 2-way coupled analysis. I have a box that is translating in x - direction due to which there is some velocity generated in the fluid around it which strikes a plate and the plate rotates due to the fluid force and thus reflects back some fluid on to the box.

I tried using two different patches with sixDoFRigidBodyMotion solver but it could detect only the last patch ignoring the other. I tried using two different solvers "velocityComponentLaplacian" under fvMotionSolver and sixDoFRigidBodyMotion in the same dynamicMeshDict but again it would ignore the first solver (in my case sixDoFRigidBodyMotion).

I spoke to few people, they suggested to develop my own solver or library. But I'm not that well versed or adept with coding and I have very little knowledge of actual physics.

I am using sixDoFRigidBodyMotion for the flow induced rotation of the plate (all other motions are constained) and velocityComponentLaplacian for the box (exactly like movingCone case).

Any suggestion on how to tackle this problem? Will mapFields work in 2 way coupling? Or is there any other solver that can do this that I'm unaware of?

Im new to Zbrush. I would like to ask about one problem.

I try insert mesh to do stitches ...but always when I try to use the insert mesh brush I get following result. See pic.

The stroke line doesnt lie on the mesh. :/ What do I need to adjust to have some nice stroke on the mesh.

Thank you very much.
