FSI - dynamic Meshing
I want to share a problem i m facing with openFoam dynamic
meshing while trying to perform FSI simulations.
I m importing new boundary conditions- displacements/velocities from an external FEM solver and put them to the appropriate pointDisplacement/pointMotionU file, depending on the solver i choose. Curiously after the mesh.update() is executed i get a mesh that does not quite follow the new boundary conditions...(?)
I tried with simpler deformations and it turns out that it would only work whenever the boundary condition at the specific moving patch is uniform.
Did anybody have such a problem before or has any advice for me?
What did you mean by saying "uniform"?
by uniform i mean sth like:
value uniform (0.1 0.1 0);
Problem starts when the boundary condition in non uniform so instead i input a list of vectors.
Hmm.., why did you use fixedValue patch, and not using the sixDoF... patch?
sixDoFRigidBodyDisplacement is not availiable in version 2.0 i think. I used fixedValue following the icoFsiFoam way.
no i mean
--> FOAM FATAL IO ERROR:
Unknown patchField type sixDoFRigidBodyDisplacement for patch type patch
Valid patchField types are :
But surely you can load the .so file to add the new patches.
hmm ok loaded genericPatchFields library but i get some runtime errors...guess i need to check some stuff first. do u have any fsi solver in mind that actually uses this 6dof patch? i only saw it on pimpleDyMfoam but it doesnt seem to help much...
thanks for your help !
pimpleDyMFoam can do the job. And sicDoF b.c patch is in another .so library, load the correct one.
