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

If the part if deforming around the joint, then:

1) double check your material properties are reasonable in the flexbody:

a) check the mass of the flexbody that it's reasonable

b) animate the modes of the flexbody to make sure they are reasonable.

But something does not add up, if the model is performing ok, but the deformations you are seeing are that large.
