multi body inertia relief

Recommended Posts

Hello everyone,


I'm currently learning HW 12 in university and I tried to perform an inertia relief analysis to a normal metal chain (4 bodies with surface contacts). I performed the inertia relief tutorial RD-1030 and it work out.

But when I tried to perform the inertia relief analysis on the chain, I didn't know how to set up the suport1 constraints and I haven't managed it yet to get the analysis going. I mostly get the Error 941 (large displacement). Seems that 6 dof constraints are not enough...


Now I wanted to ask, if it is possible to perform inertia relief analysis with multiple bodies, which are connected via surface contacts to each other?


Thanks in advance for some help!

Thanks for your help!


I have one more question:

Is it possible to run a inertia relief analysis which includes not only suport1 constraints, but also SPC constraints? for example some other objects, that habe SPC contraints
