[Gmsh] how to mesh 3d object into tetrahedrals and import the result into impact?

[Alexander Rabtchevich]

I've been trying to mesh 3d solid and import the result into Impact with 
no success.

Is it possible to mesh a body with tetrahedral, using Gmsh? When I try 
to mesh 3d with 1-st order element, the result if inspected consists 
from triangles with 2 dimensions and g=0. When I try 2-nd order, the 
result appears to have 10-nodes elements and so on.

When I try to import the *.msh into the Impact, it complains for the 
absence of material definitions. I've tried 1.0 format with and w/o 
"Save all" option, but it does not help.
