Physical Velocity !!!!
 

hi the fluent 6.1 manual says:

FLUENT allows the calculation on the physical velocity using the Porous Formulation region of the Solver panel. By default, the Superficial Velocity option is turned on.

But, how to obtain the solution in terms of physical velocity!!

What is meant by "Porous Formulation region of the Solver panel"

what steps to follow?

Thanks in advance
