Rotation of rigid body
Rotation of rigid body
(OP)
Hello all,
I have a rigid body (discrete 3d rigid - shell from solid) that I want to first translate (with fixed rotational degrees of freedom) and then rotate with the remaining two rotational degrees of freedom fixed.
When I apply those BCs at the reference point, I get the error "too many attempts for this increment".
Anybody could give any solution? I tried coarser and thinner mesh but nothing changed.
Thank you in advance!

Finite rotation boundary condition specified in multistep three-dimensional analysis. Type=velocity should be used
and while I have the unsuccessful tries I get:
Excessive distortion at a total of 2 integration points in solid (continuum) elements
Excessive distortion at a total of 10 integration points in solid (continuum) elements
Excessive distortion at a total of 20 integration points in solid (continuum) elements
Excessive distortion at a total of 18 integration points in solid (continuum) elements
Excessive distortion at a total of 32 integration points in solid (continuum) elements
Any idea on how to solve it?

I have some contacts defined. The warning/error messages I get are those posted in the previous post.
When I run the same model with "tie" contact interactions instead of friction, the model runs very smoothly...
