catamaran wave making resistance
 

Hi all,

I' m a newbie here, actually I'm gonna have to modelling wave making resistance on some catamarans with same displacement but some differences on demi hulls geometry (shapes and spaces between them) so that I know which one has less wave making resistance.
But I just don't know what software I'd use, so please give me any suggestions and even a tutorial if you guys don't mind.

Thx before....
