Class 3 Error
If an inlet mass flow rate is specified as a volumetric flow rate multiplied by a call back function of the density, for example massFlowAve(Density)@Inlet, then this will lead to incorrect velocity initialization, incorrect timescale specification, and incorrect solutions, which may not be obviously wrong, when the case is run in parallel.
This is due to a coding errror i
Set an initial velocity field explicitly, rather than using the automatic functionality.
