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

Hello,

As far as the rigid model is concerned, it ran properly. When making the part flexible however, the fixed joints I use seem to just not work (even though they are attached to the int nodes of the flexbody).

About the pivoting part, what I mean is not that the model rotates with the joint but rather it gets deformed around it. The rbe2 element where the joint is gets deformed and as such the whole body seems to pivot (as if I were pinching it by the rbe2's master node).
