Inertia Relief

[trabeshi]

Hello mates,

I'm using PATRAN 2012, and I'm trying to analyse suspension lower control are through utilizing inertia relief option,
I have created a node on the center of gravity, to select it as "Node i.d. for Wt.Gener"; however, the simulation gave "USER FATAL MESSAGE 9050" (rigid body motion),

Appreciate you help and advise,,

Thanks,

Add 'param,inrel,-2' in your bulk data section to activate inertia relief.
