Overview of Stock
Elements
Stocks elements are elements which impart inertia and memory to a system. These kinds of elements are responsible for internally generating the dynamic behavior of a system. At any point in time in a simulation, the outputs of stock elements are computed based on the historical values of their inputs. Mathematically, stocks represent time integrals.
Element | Default Symbol | Browser Icon | Function |
Integrator | Integrates values. Also can compute moving average of a specified input. | ||
Reservoir | Integrates (and conserves) flows of materials, allowing for upper and lower bounds to be specified. | ||
Pool | More complex version of Reservoir, making it easier to model multiple inflows and outflows. |
