| Dear Moab-Dev,

| I have a geodesic mesh (like MPAS or GCRM) and I was wondering what
| the best way to represent the mesh in MOAB was. It is topologically
| 2D
| but it is embedded in a 3D manifold (so vertex coordinates are
| x,y,z).
| I was thinking that I would treat the mesh as 2D, feed in "bogus"
| vertex coordinates and just use tags over the mesh elements to keep
| track of the actual mesh coordinates. This way, I keep the 2D
| topological structure (which is more important for my application
| anyways). Is this a good approach?

| Thanks,
| Chris Eldred

Probably I don't understand what you need :( 

What kind of format do you have ? netcdf? Is the mesh on a sphere / surface? 

The vertex coordinates are retrieved with "get_coords" methods, and set with set_coords methods, or use "coords_iterate" type methods in readUtil interface. 

Why not keep the full 3d mesh? what is so special about the 2d topological structure? 
Is it structured in any way? Can you use the MPAS reader or not?
