incompressible-ideal-gas #f
 
Hello i wanted to ask when I input summary of my material properties why it has "#f" on it? What it means? want to know this shows error or evertyhing is ok?

Density kg/m3 incompressible-ideal-gas #f

#f means false, or you can interpret is as "not applicable" or "unknown" here. For you have chosen "incompressible ideal gas" model, the density is an output (calculated from operating pressure and temperature) rather than a user input.

I see so it means it doesnt work. Yes you are correct I choose incompressible-ideal-gas for density, but it is integrated function in Fluent and I cant do anything about it. So its possible to fix it? do I need to do something more?
I am confused why Fluent shows error on itself created functions.

This is the expected behavior, not an error.
