Help request: Gambit optimized Mesh.
 
Hi buddies,

I am involved in meshing procees of a high speed train on Gambit. I am stuck in this stage as I can't create a good grid structure. The Only possible mesh on my model is Tet/hybrid Tgrid type. but I think it is not a good mesh. could anybody help me how to create a good dstructured mesh on this model? this is my model; http://tinypic.com/view.php?pic=4ys23bt

the yellow face is symmetry plane and i have subtracted the train body volume from a box volume to create one domain volume.

I think the problem comes from the nose and back faces of the train as they are not simple geometries and have specific mathematical equations.

If anybody want to help I can send my madel database. Many thanks in advance.
