http://www.geuz.org/gmsh/doc/texinfo/gmsh.html#Node-ordering However it makes even the interior elements to be higher order, while I only want curved elements on the boundary. > > > If this is so, what other grid options do I have to represent curved > > geometries ?

It will not be easy to do for complex geometry. Thanks praveen
