Simple Volume
fullflow.SimpleVolume
Lumped fluid volume with mass conservation only.
SimpleVolume represents an internal fluid control volume whose pressure is solved from steady-state continuity. It is useful when the node pressure must be an iteration variable, but the node energy equation is handled elsewhere or intentionally neglected.
