Hello, this is my first post. I'm trying to realize the simulation of a boat (a tow) with openFoam, in particular a drag evaluation.
the first question is: which would be the computational resources to do a good job??

I have just my pc with an intel core duo 2,4 ghz..

It depends on your judgement of a "good job", the problem size, required accuracy, whether you can wait days or years for the result, ...

Just set up a small problem on your pc to get some experience. Core duo 2,4 ghz with 8GB RAM should be sufficient to get started, but not for serious applications. For example, I think I remember having read that http://powerlab.fsb.hr/ped/kturbo/op...geDistance.mpg was simulated in 10 hours on 64 processors - I don't remember the details specs.
