[Gmsh] flat tetrahedral

Hello all

I use Gmsh to produce meshes for Impact. I discovered for myself that 
Impact is a very characteristic length sensitive program - its time of 
calculation is at least inversely proportional to the _minimum_ 
characteristic length of all triangles in a mesh. So if some tetrahedral 
appear flat, their characteristic length becomes smaller than the value 
set in geometry file. E.g. minimum defined characteristic length is 0.04 
and minimum characteristic length in the result mesh is 0.0085 
(calculated by my program).

Is there a common way to increase the "fullness" of the mesh? I use 
Netgen 3d algorithm.

Here is the geometry file of the problematic body.

With respect
