Print rotation SOL 601,129

Hello,

 

I would like to know how I can output the rotations of the node for the SOL601,129. 

I get the translation, but the rotational dof are all zero.

 

Thanks

If the grid you are printing displacements for is only attached to a solid element, it will only have 3 translational reaction forces. Solid elements only provide translational stiffness.

 

If the grid is attached to shells, beams, rigids, etc, then there will be translational and rotational reactions.

Thank you for your answer.

 

But I am using CTRIA3 element that are shells. I am simulating a cantilever plate with enforced displacement and rotations at its root.

I have all 6DOF reaction forces. But the rotations (exept for the constrained nodes in which I have assigned a rotation) are zero.

 

This is part of my input file.
