How to calculate dimensionless numbers Ra, Re, Gr
 
Hi,

I'm calculating metal casting system. I have gas and metal liquid convection flows inside two furnaces. I have to compare these two systems and probably dimensionless numbers will be the best: Ma, Pr, Re, Ra. Could anyone help me in calculating these numbers in Fluent? How to do this? By custom filed functions?

Thanks in advance!
