efforts progress, grasshopper

Hi there, we need a little help.

We have a mesh imported on rhino from blender which represents an architecture. We'd like to understand how the efforts progress works on it under the influence of gravity in order to locate the points within the mesh in which we can place the structural fibers. Does anybody have any program that can be of example? Can someone give us advice on how to structure a program on grasshopper which could be used for this purpose?

Thanks
