Hey guys,

For the past couple of weeks I have been beating my head against a wall trying to do a static simulation study on a race car chassis part file. The error I keep getting is the "unstable model, restraints may not be adequate" one. I feel like I have tried everything to fix this but to no avail. I have checked the "use soft spring to stabilize model" box, and that didn't help. I have added over 400 bonded contact sets between all the tubes. I have tried using fixed geometry fixtures all over the place and that hasn't helped either. I really don't know what else to do to try to find where the problem is. Attached is a picture of the meshed model. ANY help would be greatly appreciated. I would be happy to provide more info if needed.

Thanks in advance,
-John
