parametrisation of stress pattern / quads

Hi Everyone, hi Panagiotis.

I want to have panels (triangles or quads, doesn't mater) that follow stress lines.

For that i use stress pattern + quads. Problem, is that in places where stresslines

fail to create enclosed contour there is no panels. Whatever i tried - i cannot make perfect stress pattern, maybe jeometry is too complex. Any ideas to fix that?
