The modulated internal flow source is a modulated flow source on its secondary side. The primary side provides the power needed by the flow source. This element can e.g. be used to model a DC current supply together with the power cable that draws the required energy from the grid.
The flow source has its secondary causality stroke away from the source. Its primary causality stroke is free.
Potential variables: e1: Bondgraphic effort variable of inflow f1: Bondgraphic flow variable of inflow, normalized positive for flows into the model e2: Bondgraphic effort variable of outflow f2: Bondgraphic flow variable of outflow, normalized positive for flows out of the model f0: Flow to be generated (modulated input signal)
Equations:
f2 = f0
e1*f1 = e2*f2
