Hi,

Is there are a possibility to work in dimensionless form in fluent ,If yes how

thanks alot

hi, you can work in dimensionless form!calculate your values and just work with that whatever the units are!!

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.

Thank you for answer

Please can you explain the manner in detailed How can I defin the governing equations in nondimensional form and how can I define the values of properties

Thanks

I don't think I understand you - what do you mean? 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.
