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

Update: By checking the plots and not the graphics, the model seems to work fine. May it just be a matter of graphics?

What I also found weird however is the fact that while the displacements are small throughout the model, the deformations on the flexible body are huge (displacements ast +-1 mm, deformations at 1e6 mm, numerical error I assume)
