FSI boundary conditions
I m currently facing a problem with my fsi application in openfoam. I ve coupled openfoam with a fem solver and problems arise when i set the moving wall velocity equal to the velocities i get from the solver.
i am familiar with the added mass problems in fsi but i seriously think i am misusing the commands makeAbsolue and makeRelative. Apparently the grid is deformed with a velocity equal to the boundary.
My question is: does anyone know if by using the above mentioned commands there is no longer need to explicitly set the velocities on the boundary? I m asking cause when i dont disturb them my results look quite good.
