Hello everyone,

I have two connectors with the same declaration; i.e one flow and one potential variables

Connector1
flow SI.MassFlowRate Qm;
        SI.Pressure p;
End Connector1;


Connector2
flow SI.MassFlowRate Qm;
        SI.Pressure p;
End Connector2


Except the name of the connectors (connector1 as incoming and connector2 as leaving flow), the rest is the same in both cases.

Since the flow is reversing while simulating, despite I followed the signe convention (sume of in and out is zero), I tried also using input and output for the flow in each connector. The flow still reversing at some junctions.

Can anyone help me what I should consider in this situation?
PS: I am in the learning curve to apply modelica for a real project.

Thanks
