pywr.parameters.FlowParameter

class pywr.parameters.FlowParameter(model, node, *args, **kwargs)

Parameter that provides the flow from a node from the previous time-step.

Parameters

modelpywr.model.Model

nodeNode

The node that will have its flow tracked

initial_valuefloat (default=0.0)

The value to return on the first time-step before the node has any past flow.

Notes

This parameter keeps track of the previous time step’s flow on the given node. These values can be used in calculations for the current timestep as though this was any other parameter.

__init__(*args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.
