Facing problem in performing Inertia Relief Analysis

Abhishek Sharma_21900

Hello,

I was trying to run an inertia relief analysis on a suspension using optistruct. I have used both INREL -2 & -1 options but in result it is showing high deformations. As I am beginner in hyperworks so it is possible that I have defined Support1 constraints incorrectly. Actually I am confused about constraining a rigid body motion. So seeking help.

Please help me in this regard.

I am also attaching ".fem." file of my solved model. Please see to it and guide me. Please let me know where are the mistakes.

here are a couple extracts from the help, and a tutorial on inertia relief.

 

If you use PARAM,INREL,-2 you don't need to specify suport. Otherwise, yes.

Adding some pictures migh help people to better understand your issue.
