Dear All
I looked at foam-extend4.1 and overset feature of solids4Foam. As it seen the overset tutorial with serial run is OK. But I want to know, does the code run with parallel simulation, if yes, How?
Thanks

Yes, solids4foam can be used in parallel.
You have to use
decomposePar -region fluid
decomposePar -region solid

Then..
mpirun -np "cores" solids4foam -parallel

I have problem with parallel in overset tutorial. for example I use
decomposePar -region fluid
decomposePar -region solid
mpirun -np 4 solids4foam -parallel
But, the run crush after checking Selecting dynamicFvMesh newSubsetMotionSolverFvMesh

Selecting fluidModel pimpleOversetFluid
Selecting dynamicFvMesh newSubsetMotionSolverFvMesh

Do you engage with this problem?
Thanks

It seen, the problem comes from subSetMotionSolver that not work with parallel. Can we use another dynamicMeshSolver in this case?
