Hello,
There is the "rotation" option under the "translation" but it doesn't operate so easily than the definition of translation. Why? How can I define a simple rotation (with certain angle value) for a body?
Mechanica shows the next notice continously:
Thanks:

Hi Roland,
You can't directly apply rotations to solids, because (as I understand it) constraints actually apply to nodes, and nodes only have three DOFs, not six. Same thing applies to moments, although there a Total Load At Point will get round the problem.
As the message says, you should be able to do it through a rigid link. Here's an extreme example:
Enforced displacement, tangential direction, more than 1 revolution
(this also mentions an alternative approach which is to use a cylindrical csys and apply a theta constraint).
Hello Jonathan,
ok, I have wrtitten that the using of rigid link is OK for the rotation. I define the rigid link between a point and a surface but it doesn't operate.
This is my testmodel with cylindrical coord. system:
It is the point and the surface for the rigid link:
And the displacement:
Based on results, the rotation doesn't occur.. What is wrong? The rigid link?
Thanks
Roland
A couple of thoughts:
Hi,
I've used Creo 3 M110 for creating the attached file.
I've no used rigid link related to a point for imposing a rotation.
In my example the goal was the rotation of 2 mm (arc) and I done this in two manners: by imposing the linear rotation and the angular (radiants) rotation.
Bye
