I would like to use a mass flow rate as the variable in expression list in CFX-Pre. The name of inlet plane of the domain is 'in'. I name the variable as 'mdot' then define it in the 'expressions' tab as

massFlow@in [kg s^-1]

When I use the 'Evaluate' tab to evaluate 'mdot', it says that this variable is dimensionless. If I define it as

massFlow@in

At 'Evaluate', it pass with a very hugh number that is not the magnitude of mass flow rate. So how to define mass flow rate as the variable in CFX-Pre?

Thank you very much for your consideration.
