Using →ComplexInteraction
this component allows to logically connect two flows influencing
two stocks A (connected to portA) and
B (connected to portB). The formula
for the resulting flows (using
Newton's dot notation) has linear and
nonlinear terms:
The coefficients are given by parameters, which are 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 flows via output connectors (y_A,
y_B).
a_0 = -1, b_0 = 1 (other coefficients set to
zero), and hasFactor = true a bidirectional
flow can be modeled, whose rate is given by the input
u (positive inputs indicate a flow from
A to B).a_0 = -1, b_0 = f (other coefficients set to
zero), and hasFactor = true a
broken transition can be modeled, with the proportionality
factor f indicating units of B per unit
of A.polA and polB allow to
give visual cues with regard to polarity in the diagram.
