Flexbody constraints

Hello,

I want to constrain a flexible body on multiple points, using rbe2 and fixed joints. When I use more than 1 joints I get a redundunt constraints message and the simulation stops due to lock errors. I tried removing some of the fixed joints, but then the flexible body just "pivoted" around the remaining last one.

Is there a more proper way to constrain flexible bodies on multible points?

Thanks,

Josef

Does it crash at approximately the same simulation time every time?

Try stopping the dynamic simulation just before the crash and do an Eigen mode analysis on the model and see if this gives you some answers. Maybe some strange frequencies are excited in the flexible body.
