Dynamic Simulation issue

Dynamic Simulation issue

Dynamic Simulation issue

(OP)

I am running a dynamic simulation of a cam mechanism. (Friction and contacts involved. Graphing Time vs Torque.)
I ran the same analysis just changing STEP value in Solution Attributes but the maximum torque I obtain in the graph varies excessively, as you can see in the following table ; the values of 200, 400 or 600 steps "might" be fine, (the difference might be because of the accuracy)..., but what about the 300 step result!!!????

STEP TORQUE
200 - 2300 N-mm
300 - 12850 N-mm
400 - 5078 N-mm
600 - 4141 N-mm
Im sure there is something Im doing wrong.
I ran this twice with each step value...same results..Im in NX8.5.
Do you have any clue about this???
Thanks and best regards.
