tidal turbine
 

Hi,
i am new to ansys cfx and just trying to get my head around it and could use some help :-D?

i would like to use an actuator disk in order to model my turbine.
My first problem is so that i do not know how to tell cfx to not treat my disk as a wall but rather to ignore the disk. Later i will include expressions to simulate the forces from the blades.
I used a Boolean operator to subdract my disk from my enclosure. i hope this information is sufficient.

Thanks for your help.
