May 13, 2021, by Michael Wetter:
Changed boundary condition model to prescribed pressure rather than prescribed mass flow rate. Prescribing the mass flow rate caused unreasonably large pressure drop because the mass flow rate was forced through a closed valve.
This is for #2488. -

Corrected wrong use of replaceable model.
This is for issue 921. -
