Hi I created a thin rectangle (attached). I generate a 3d mesh (by pressing MEsh -> 3d) and I try to save the resulting mesh in the cgns format using default options. Segmentation fault occurs. I was playing a bit with this and for different rectangle thicknesses there was no segmentation fault, but the patches under <Boundary Conditions> in the resulting cgns file were incorrect. They contain wrong set of triangles, some boundary triangles are not in any patch, and usually there was even wrong number of parches.
