Hi,
I use OpenFoam v1912 to simulate the movement of the 2D object (hydrofoil in forced pitching motion and free heaving) under the force of the fluid .
I tried it using pimpleDyMFoam but mesh deformation is too big to simulate.
So now I am working on it by using oversetmesh function.
I ran some tutorials about oversetmesh but I could not use oversetmesh(overPimpleDyMFoam) with 6DOF.
How can I use oversetmesh with 6DOF?

Include "libsixDoFRigidBodyMotion.so" in controlDict like
Code:
libs            ("liboverset.so" "libfvMotionSolvers.so" "libsixDoFRigidBodyMotion.so");
, then you should be able to use sixDoFRigidBody motion solver.

HTML Code:
valid solver types:
14

Hi Michael

Do you know if is possible to model the advection of a solid inside a stream using overset methods?

Since all the functions in SolidBodyMotion require to specify a type of motion for the mesh inside (linear, oscillating etc), but for this case it would be "free motion" due to advection.

any help would be appreciated.

Hi frantov,
From my knowledge, it is not possible to couple overset with this motion in current OpenFoam. The solid is free moving by the force of the fluid, so itís a Fsi problem and you have to know the force exerted on the solid from the fluid. Maybe foam-extend has this capability, but I am not very familiar with it.

Thanks for your reply, yes that's what Im interested an overset mesh with free movement. I'll keep exploring OF. Good luck on your simulations!

Hi frantov,

Have you figured out this problem, I'm also interested.
