View factorgen throws a floating point exception when used with thermal 3D baffles in more complex geometries.
in this case extending the length of a baffle by 20mm causes a failure.
I attach two cases one where it works and another where the small change in the baffle sizes causes the exception.

Changing the Viewfactorsdict appears to have no effect.

This is with openfoam 2.3.1. with the newly updated facesAgglomerate from 2.3.x
