Apply moment to GMO

azarov.nikitin · July 27, 2019, 12:03

Hi!

I have a GMO in my simulation which is coupled to the flow.
The GMO is allowed only to rotate around one axis (i.e. pitch).
So, the pitch motion is measured by an angle called theta.

I want to apply a moment to the GMO which is a function of theta and has the following formula:

Moment=100*(omega)^(1/51),

in which, "omega" is the time derivation of "theta".

How can I do it?

Regards

As far as I know, you can't prescribe a moment to a GMO. Customization might the way to go. You can, however, prescribe an angular velocity and the solver will use it to calculate the rest.
