Hi Jan,nIt's best to ensure a conformal mesh (no use of contact) to get accurate results, especially if solving over a wide frequency range. The DOF interpolation that exists when meshes don't match in contact regions introduces some 'noise' in the solution, which is probably what you were seeing - this issue is reduced as the mesh is refined, but doing so also increases the computational cost.nThere are many meshing tools available, including virtual topology or patch-independent meshing, which can help with meshing problems due to small features or slivers. I would recommend getting a conformal mesh (multi-body part, no contact) using these meshing tools.nRegards,nSheldo
