! $Pin = massFlowAve("Pressure","inlet"); ! $Pout = massFlowAve("Pressure","outlet"); ! $dp = $Pin-$Pout; ! print "The pressure drop is $dp\n";

Note: Function-specific Perl subroutines do not allow phase-specific evaluations; that is, you can get only bulk results (such as mass flow for all phases). A workaround is to use "evaluate" subroutine, which evaluates any CEL expression.
For example instead of
! $val = massFlow("Inlet", "Water") # Does NOT work
you need to use:
! ($val, $units) = evaluate( "Water.massFlow()\@Inlet");
