I have an L-shaped section which I am trying to mesh up. The inside corner of the "L" is radiused. I have partitioned the section perpendicular to what I would term the "axis of extrusion" of the section. I have partioned the section itself into 3: one for each leg and one containing the radius. Someway along the section I can no longer create adjacent meshes because I am getting the error message: "selected regions cannot be meshed because they cannot be made compatible with existing meshes". Any idea what is causing this? Can I check that adjacent cells are compatible? I have a mixture of swept and structured meshes - but I don't see why this should make any difference.
