Information

This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.

Growth can be used to model an inflow to a stock from a source with infinite capacity outside the border of the system in focus. The rate of flow can either be set by the real input u (hasConstantRate = false) or by the parameter rate (hasConstantRate = true).

Notes

The rate of flow has to be non-negative as the connected stock should never be drained. A negative rate of flow will be set to zero internally by the component.

If the connected stock might also be drained, →ExogenousChange should be used.
