feedtwin.solve.network.Node Class Reference

Public Member Functions
bool	is_fixed (self)

Static Public Attributes
float	pressure = None
float	demand = 0.0
str	phase = None

Detailed Description

A point in the network where a pressure is defined.

Args:
    id: Unique identifier. These are the tags on the P&ID.
    fluid: Species name or alias -- resolved through the property layer.
    temperature: Static temperature [K]. Given, not solved: this phase is
        isothermal.
    pressure: Fixed pressure [Pa] for a boundary node, or ``None`` for a
        free node whose pressure is solved.
    demand: Mass flow drawn *out* of this node by something outside the
        network [kg/s]. How an engine's appetite enters a feed-system solve
        without modelling the engine.
