No - I did not check if at one physical location if I have more than one node. Sorry but I am not sure what you mean by detection method. > -which was the export format? > I am exporting it in standard Gmsh .msh format. you say you want the true mesh, the physical mesh.

So, when I exported the mesh, I could see that there are nodes which are in $Nodes section but are not part of the finite element connectivity in $Elements section. In fact these extra nodes were created at the exact physical locations where I had specified the points to define a B-spline bounding line. Nothing wrong with this except I do not need these nodes for my FE program. Specifying a physical group as above however enables the export of only those nodes that "belong" to the physical surface - exactly what I need.
