The bar doesn't move over to the rectangle. The rectangle is fixed. What should I check?
I createt a similar situation as yours and experienced the same strange behaviour.
I deleted the constraint and recreated it once: same strange behaviour.
I deleted the constraint and recreated it again: same strange behaviour.
I deleted the constraint and recreated it a third time: all turned out as expected.
With the strange behaviour I got two messages:
- orange: ...redundant constraints
- black: ...dof remaining: 0
If it works well it is only:
- black: ...dof remaining: 2
2 is correct as the bar can move along and spin around the z axis of the element coordinate system.
I have no idea what puzzles the solver that it fails in this case. But I'm curious if this can be fixed easily.
