The FlowPort_Special is the corresponding connector to the StockPort_Special and will only connect to these. While usually the rate of flow is determined by a flow component, in the case of dynamic stocks (e.g., higher order delays) the rate of outflow will be determined by the stock component and transmitted to the connected flow using the variable data.
It has the following connectors:
| CONNECTOR | TYPE | DESCRIPTION |
|---|---|---|
| data | Real |
Rate of flow to be observed by connected flow element |
| rate (flow) | Real |
Flow that affects the stock |
The FlowPort_Special connector class is used as MassPortF by Peter Junglas for his approach to SystemDynamics modeling [18, Chapter 12] (see here for a system dynamics Modelica library published by Peter Junglas) and has been simplified for the Business Simulation library.
