Partial model extending from the →GenericFlow base class. This is a generic class for unidirectional flow components where the value for the rate at port A (A_rate) can be set by an equation. The rate has to be positive; negative values will cause a warning.

Notes

• The unidirectional flow will only allow flows from source (A) to destination (B). A positive rate is associated with the A-side port (portA) and will thus drain the stock connected to it.


• The rate of flow at port B is given by the equation B_rate = - A_rate.

• The flow-element will observe the Boolean flags of the connected stocks (e.g., stopOutflow or stopInflow) on both ports which may override the intended rate to give zero flow.

• Minor modifications for useA_rate and useB_rate expressions in v2.1.0.
