Definition of flow and potential

The flow quantity is defined by the volumetric flow rate given in .

The potential quantity is given by the pressure drop given in Pascal () by default.

In accordance to the existing libraries the connectors shall be numbered. Thus at a one-port there are pins 1 & 2. The pressure difference shall be given by


As suggested in Lenk2011 the volumetric flow rate is charted as arrow from the pin1 into the element.
