returns a structural link between two solid geometries
Description
The structural link between solid A and solid B is a (optional bended) contour shaped rod or tube. Depending on the paraemters it is either a full solid or a lightweight grid structure. There are different heuristics to link the two solids:
a) shortest connection of both mass centers
b) direct connection of centers at the center of the attached surfaces
c) connection using attached surfaces and ez vector (Bezier)
d) connection with specified surface vectors
e) connection with specified surface points
f) .....
The vertex list VL contains first the vertices attached to Solid A and the the vertices of solid B. The facet list FL contains first the facets of the wall (2*nv), and then the facets of the cap on Side A and then the cap on side B. compiled from experiment exp_2012_11_12 and used in exp_2012_11_15 and exp_2012_11_22.
