Flev is on a distinguished road
Hi,
I'm a new user of CFX 11. I want to run a simulation of a hull to compute the flow of the water (and air) around it.
I have designed the hull and imported it in design modeler.
Now, what should I do?
Should I create the fluid domains in the design modeler with boxes of definite dimensions?
Or what else?
I must create two different boxes for the water domain and for the air domain. Is it correct? Or not?
Then I must subtract the volume of the hull from the fluid domain in order to mesh ONLY the fluid zone.Is it correct?
Or these operations will be done in the CFX pre? How?

Thanks
