Default GAMBIT - Cooper Scheme

Hello,

I'm stucked w/ a meshing problem while using a cooper scheme. I get this error message : Assertion failed in BarrelCapStack. cc, line 57: NULL != next_cap while meshing volume.17.

Here is the description of my geometry: I have a 1 single volume that COULD be disretized in 3 volumes : the central one would be a regular hexahedron ; the two exterior ones would be two twisted hexahedra. total : 14 faces (6 source faces for the cooper scheme)

any idea why the cooper scheme does not work fine here?

Cheers, JB

A cooper scheme fails only if a geometry converges to a pipe. why exactly do u want a cooper; A mapped hex could replace a cooper. But it all depends on what your lookin for!

I think I just Cannot avoid a cooper : I have no choice but meshing several source faces of my volume w/ a Tri-pave scheme. But what do you mean by "A cooper scheme fails only if a geometry converges to a pipe" ? I'm sorry, my english is not perfect at all. Anyway, If someone got a similar problem, I found a trick to avoid the pb: just split the initial complicated volume into several simple ones. That way I don't get error messages anymore.

Cheers,JB

Yes, I did have a similar problem and someone did say: Split and win. But , I had certain restrictions on splitting the volume. So, I said see what your lookin for and then make an optimum choice. Regards Samir.
