Tommy O Brien Guest Posts: n/a	Hi all, I am trying to model 3d flow through two 45 degree intersecting pipes using Gambit to mesh and Fidap to solve. I am using the FSI capabilities of Fidap for deforming walls and remeshing. The flow through the geometry is okay but the walls are not deforming. I think the problem may exist due to the mesh interface between the wall and the fluid. I am unsure as to the degree of linking I have to adopt between the wall mesh and the fluid mesh. Any thoughts? All comments deeply appreciated. Tommy.
