Relation between geometry file and mesh file

Hello,

I am working with 2D geometry files with curved edges. I have an associated mesh file as well. When reading into Netgen 6 I tend to have some strange behaviour while the same pair in Netgen5 work fine.

Is there some change in the coupling between curved mesh and geometry file?

I am attaching the geometry file, mesh file.

Some indices have changed from 1 based to 0 based. Create a new mesh with netgen6 and use that or save it and compare which indices are 0 based and 1 based and substract 1 from these. I guess creating a new mesh is the faster way.
