Using →Transition this component allows to model a transition from stock A (connected to portA) to stock B (connected to portB) at a rate given by the parameter rate. The parameter rate is multiplied either with 1 (hasFactor = false) or an exogenous factor u (hasFactor = true). Upon setting hasRateOutput = true the component will report the current rate of flow via an output connector (y).
rate = 1 and hasFactor = true a unidirectional flow can be modeled, whose rate is given by the input u. Note that negative values will be clipped to zero as only flows from A to B are permitted.polA and polB allow to give visual cues with regard to polarity in the diagram.rate was not used in v2.1.0
