Hello CFD clan,

I am trying to run a fluent simulation within the model (pic attached). I have given Inlet BC as "mass-flow-inlet" and outlet BC as "Pressure-outlet". I have used transient profile to create .prof file from graph (pic attached) for mass-flow-inlet BC.

When I am trying to plot the velocity and mass flux definitions, I observe that the values from transient profile are being plotted in velocity definition plot , not in mass flow rate graph .

If I have given mass-inlet-flow as inlet BC then why I am getting those values in Area weighted average velocity magnitude (m/s) ?

PFA pictures for your reference

Graph from which values are taken to create transient profile
Inlet Bc condition (Mass-flow-inlet)
Velocity graph definition plot
Mass flow rate definition plot

Thank you
