This package contains stock ("reservoirs") elements of the system dynamics method.
While stocks do have an inflow and an outflow port (indicated by two small arrows pointing into and out of the component respectively), this designation will in general not be relevant for their behavior with regard to flows:
A stock may be filled or drained on either side - the flow element connected to a stock will determine the direction of flow!
Nevertheless, it is good modeling practice to follow the convention of connecting flows that are strictly inflows or outflows to the corresponding stock port.
There are two important cases, where closely sticking to the inflow and outflow designations is very important:
