It depends on
  - which type of facets you are using (triangles, quads)
  - which type of vertices coordinates you are using (cartesian, cylindrical, 
spherical)
  - which type of interpolation you are using over verticed facets : linear, 
quadratic, cubic..
Moreover, the shape of the volume is of importance : without / with holes (ex: 
sphere / torus),
   holes internal or connected to the outer space, etc...

All this stuff is about finite elements. So, many references about F.E. should
be convenient.
