## creo simulation ; how can i set constarint in nonlinear analysis

it very simple

i want to know stress of twisted part on 1dgree.

could you let me konw how set "prescribed rotation" in constraint

thanks.

Hi,
you have to set a cylindrical coordinate system and refer the translation to its theta.
Remember to flag the interpretation like radians.

You can check out the result by making a displacement measure; it's being in mm, so it's measuring the arc of displacement.
You can't measure directly the angle; the measure "rotation" serves for beams or shels nodes that have also rotation degrees. The solid one doesen't have rotation degrees.

This thing can be make both in linear and non-linear analyses.
Bye

Cylindrical coordinate system - watch this limitation for twist situation.

Interpret Angular Translations in Radians  - Beware that this cannot be used for Large Displacement.

Hi,
What about to constraint displacement of one end of the part and apply weighted/rigid link between the other end and a point, say on the axis of rotation, and then apply a prescribed rotational constraint to the point with respect to the appropriate direction.
