I've been simulating a NACA0012 airfoil with a rough upper surface and a smooth lower surface while pitching. To induce the forced motion in this case, I'm using the SURFACE_MOVEMENT=DEFORMING with MARKER_MOVING= (UPPER, LOWER, TE) where UPPER and LOWER have different roughness. These are three different markers along the airfoil surface, naturally connected, but it seems that once the deformation to mimic forced pitching starts, the shared nodes between these markers seem to be displaced twice. It seems that this could be a result of separate displacements of each marker so that the node that's shared is being applied the deformation twice.

An example can be observed in the attached files. These correspond to the shared leading edge, and the blunt trailing edge.
