ProportionalSwitching models the exchange of "mass" (conserved matter or information) between two stocks as a bi-directional flow. The rate of flow will be proportional to the amount in the connected levels times the fractional rate of flow given by the input u:
| input u | direction of flow (for positive levels) |
rate of flow |
| u ≥ 0 | flow from A to B |
|
| u <= 0 | flow from B to A |
|
useAbsoluteLevels the direction of flow may be reversed by negative amounts in the connected stocks, which is possible, if the stocks are information levels (material stocks by definition cannot become negative).useAbsoluteLevels may be set to false as the amount in the stocks cannot become negative.
