problem with 3d-geometry
 

Hi, I have a LNT (Low NOx traps) captured with a scanner 3d. I must divide the volume and surface of the LNT in some sections. The problem is that iges file is constituted of many surfaces. I thinked to merge surfaces to create a single surface, but then how i can to divide it?

Tools?
 

What tools are you using?

I'm using Gambit. I should split the volume by surfaces to use boundary layer.
