millipede stress "0"

Hi

How are you doing ? :)

it's been a month that i started to learn grasshopper and im working hard

 i just faced a problem in "millipede" plugin that i don't know how to fix it.

the max stresses are all "0" and i don't even know if i put them togather correctly

here is my design : some points that gives us random curve which create a surface and i wanted to use that surface in millipede and see it's stresses

i define the "mesh " , "supports" and a load 

is there any video to learn millipede !! i can't find some1 to learn from ...

Thanks ;)
