rotating reference frame

January 18, 2005, 14:00

I have a projectile with canted tail fins. These tail fins cause the projectile to spin at a certain rate (OMEGA) relative to the airspeed.

I'm having trouble setting up the model to get this rotation. Do I set the fluid zone as rotating? Do I have to set the rotation of the fluid to negative OMEGA? If I do rotate the fluid zone, what do I do with the body? Is it better to set the fluid zone as stationary and rotate the body?

I appreciate any help.

Thanks, Jason

Hey, I know it's been a long time but did you manage to solve your problem? If yes I would like to hear it because i have a problem similar to yours.
