Hello Keyur, thank you for respond.

I'm sorry but, how should I do that? Because, I know how to create parameter in fluent, but in boundary conditions, fluid properties, where this parameters are created with the units of velocity, density, viscosity, etc. I do not know how to create a parameter form zero in fluent.

Other thing, in the parameter tab on WB, the parameters  have defined some properties, and I can't put where the value is, something like: "P2", because fluent show me a message like: "P2" is not a valid numeric value, or something like that. I guess it is because it's defined as a constant value.
