In a post in wich we have participate Carlo says:

"I'm trying to observe and compare kangaroo to ANSYS (FE method) in a small example in my work.

I'm well known to the compatible unit systems (m - N - Pa) (mm - N - Mpa) etc.

I presume spring stiffness can be chosen as A*E/L if I want to model a beam. (L = total length, A = cross section, E = 200GPa steel)"

I hope this helps a little bit ;) This is the same reasoning that I've used to my work with Kangaroo ;)

That's certainly the approach I've taken, it would be interesting to see the results of any validation you carry out of a kangaroo model.
