Characteristic length stats

[kkiesling]

Can calculate the characteristic length for various entities:

• For all triangles in the geometry (or per surface or per volume), create a distribution of the characteristic length for the triangles. Characteristic length for a triangle (or any 2D entity) L = sqrt(area).
• (may not be as helpful) Calculate characteristic length for each surface (not sure if a distribution is helpful here or maybe just a listing of the CL for each surface). Again, L=sqrt(area) (would need to calculate surface area of each surface).
• (also not sure if helpful) CL of each volume (L = Volume / surface area)

All of the these stats may or may not be helpful. I think the distribution of the triangle characteristic length for the whole geometry, each surface, or volume would be most beneficial.
