[Gmsh] High Order Mesh

[Christophe Geuzaine]

Dear Brian, 

The mesh is indeed curved - but the curved triangle edges are just represented as broken by default to speed up the graphical rendering. Increase

Tools->Options->Mesh->Aspect->High-order element subdivisions

to improve the rendering.

Attached below are examples of what I am having problems with. The first screenshot shows the mesh in first order, second screenshot shows second order. Instead of curving the mesh around the model for second order, it splits it into two linear elements.
