Problem in giving the angle of throttle valve in flow simulation


Hello all,

I am doing flow simulation in NX thermal/flow. I have a throttle vale inside a tube. The angle changes from 0 to 90 in steps of 10.. Is it correct to give it in flow surface as rotational parameters. It asks for the option of motion type and rotating rate.


I have give motion type as rotational and motion rate as 10 degree/sec. Is it correct or can any of you give suggestions on it. 


I have just attached the file. Unfortunately, it is in German.


Should I use any other options?
