Thank you for your help so far, I have maple 18.02 installed.

You cannot see any movement in the results because all the initial conditions are set to zero.

I iterated out that the model works for up to 89 bodys on my system but for 90 or more the simulation fails.

I work on a windows 7 pc with 16 GB memory and an Intel Core i7 cpu, but I detected I have the only the 32bit version of Maple installed.
