# Print rotation SOL 601,129

Creator

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.

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.
