As your mesh is roughly spherical, you may be able to make a difference 
using it this way:

Add an inside vector to the mesh.

Use a difference of the mesh, a slightly scaled down copy of the mesh, 
using a scale statement, and a box or plane.

It can work as you seem so have a totaly convexe and relatively simple 
overall shape.
