Description

Demonstrates array composability by chaining Flash calculations in a two-stage separator:

  1. Stage 1: Flash feed at separator conditions -> liquid and vapor
  2. Stage 2: Flash Stage 1 liquid at stock-tank conditions -> final oil and gas

The liquid composition output ("x") from Stage 1 feeds directly as the composition input ("zi") for Stage 2, demonstrating the array-in/array-out design.
