Hello,

i'm doing a transient analysis of a thin metal plate (automotive part) that is moved and rotated by robot manipulator. The part is fixed in a couple of places where i set fixed support. A coordinate system is attached to one of these points. I set accelerated movement without rotation of the plane of the part using accelerations from the tab 'Inertial'. It works. 

In oder to study the effect of rotation on the behavior of the plate, i wanted to set the angular velocity ans acceleration. But this did not work. Rotational velocity is missing in the tab 'Inertial'. Acceleration can be set, but a message 'You have applied an invalid load for the current analysis' appears.Maybe you have some ideas?

Use the loads called:

Rotational Acceleration

or 

Rotational Velocity

 

See this video on how it (Rotational Velocity) is done on a blade structure for instance:

Thanks. That was the first thing i did. But it discusses static analysis. In static everything works. But in transient analysis all is not so simple. For example, there is no option to apply rotational velocity (i use Transient analysis with MSUP), only rotational acceleration. Ok, i chose. But it gives message 'You have applied an invalid load for the current analysis' . Unfortunately, i have not seen a video where rotation was used in transient analysis.
