Flows

Flows fill and drain accumulations. The unfilled arrow head on the flow pipe indicates the direction of positive flow.

The default flow type is the uniflow, which flows in one direction only. You can also use a biflow (bi-directional flow).

To place a flow on the diagram

  1. In the Build toolbar, choose a flow type from the Flow dropdown menu.
  2. Click the flow tool. The cursor will change to a flow icon.
  3. Click and drag to add the flow, and define its start and end. Click a stock or other variable to connect to it as you add the flow. You can connect both the start and end points of the flow by clicking a variable, then dragging to another variable.
  4. In the Properties panel, enter an equation and other properties.

    For more information about placing, naming, and editing flows, see Working with Building Blocks.

To create leakage flows for conveyors

Second and subsequent outlfows for conveyors are automatically defined as leakage flows. Use the following procedure to add and define a leakage flow for a conveyor.

  1. Add a second (or subsequent) outflow to the conveyor.
  2. Select the second (or subsequent) flow.
  3. Click the Equation panel.
  4. In the "Options" section, use the Leakage, Leak integers, and Leak zone options to define the leakage represented by the flow. For information about each of these options, see Flow options.
  5. In the "Parameters" section, specify the leakage fraction. For more information, see Flow parameters.
