Large Rotations

I preffer imposing large rotations as NLGEOM displacements on the rot node.
Be sure to set up True Scale and Time Increments for a correct animation. I have not been able to reduce the size of the vid file to visualize the example.

That’s what the OP of that thread (Rotation control doesn't work) did. Prescribed rotations (UR1-UR3) applied to ref point of a rigid body constraint are turned into ROT NODE displacements in PrePoMax. No need for keyword edits.

:no_mouth:¿How do you do it without custom cards?

If you set this in your file:

It will be automatically converted to:

*Boundary, Amplitude=Tabular-1
428, 1, 1, 0
428, 2, 2, 0
428, 3, 3, 0
429, 1, 1, 0
429, 2, 2, 0
429, 3, 3, 1

¿Is the ref always fixed when the BC is translated by prepomax?

It’s fixed only because I set U1-U3 to 0. I can leave it as “Unconstrained” and nothing will be added under *BOUNDARY for those DOFs.

Thanks. Mecway seems to work different.
