New to kangaroo, having trouble understanding its functions

Hello,

I am introduced to kangeroo for the first time (very new too grasshopper as well), i was given a script which after some speculation i assume it: simulates/calculates an outcome geometry (deformed) which withstands a certain applied force to the original fed geometry. 

I wanted to experiment with different sorts of starting geometry, so i used a populated 2D rectangle, using the points as input for a voronoi, and scaled it along the Z-axis to create a loft. When I toggle on kangeroo, the lofted mesh disappears but does not give any error, if only I reduce the number of points to 4 or 5, it does what I want. So i was wondering where might have gone wrong. and furthermore, i was hoping if someone can introduce me to some other interesting things I could experiment with with kangeroo at a first timer level. I have attached the script and rhino file since i used the points referenced from rhino. Hope i can get some hints, much appreciated.

Cheers


P.S. I have previously posted this in general discussion but just found out about this group, so I will move my post here.
