Information

This is the System Dynamics controlled restricted Outflow element, whereby the rate itself is determined by a single variable in its laundry list. This element is a restricted rate element with the additional feature that the upstream level can control the flow by telling it that it is empty. This is accomplished by a Boolean control signal from the upstream level to the rate element.

The controlled outflow element should e.g. be used to model the drainage of a kitchen sink. Water can flow out of the kitchen sink only as long as there is any water left.
