Hi,
a small update on this. I recovered the fluid-openfoam-rbf case for the perpendicular-flap tutorial from here and I tried to run it with RBFMeshMotionSolver.
It works both on the v-2012 and v-2212 versions, so no compatibility issues are present.
I noticed that all the FSI combinations in the perpendicular-flap tutorial use, on the fluid side, a single interface on faceCenters. I generally use 2 interfaces, one on faceCenters to write forces and one on faceNodes to read displacements.
May this be the source of the problem?
Thanks
claudio
