 June 1, 2007, 13:13 Re: Non dimensional calculations #3 jasond Guest   Posts: n/a Yes. Sort of. In the past, I created a new material (Define->Materials...) with unity viscosity and density equal to the desired Reynolds number. Then, generate the grid nondimensionally and that is it. It gets harder if there is heat transfer involved, but I guess you could do the same thing.

Actually, I should also check that I remember correctly what I did. I'll do that tomorrow, but you should keep in mind that this is not really a standard use of Fluent, and it shouldn't make any difference anyway.
