Model of a pipe with no flow resistance, no heat loss and no transport delay.
This model can be used to replace a replaceable
pipe model
in flow legs in which no friction should be modeled.
This is for example done in the outlet port of the
base class for three way valves,
IDEAS.Fluid.Actuators.BaseClasses.PartialThreeWayValve.
allowFlowReversal=false
.
