Two-phase envelope traces in pressure-temperature space.
2 functions
PO.EoS.Envelope.PR(zi, props, output, kij, nPoints)
Phase envelope using Peng-Robinson EoS. Output: 'bubble_T', 'bubble_P', 'dew_T', 'dew_P' (arrays), or 'cricondenbar_P/T', 'cricondentherm_P/T', 'critical_P/T' (scalars).
PO.EoS.Envelope.SRK(zi, props, output, kij, nPoints)
Phase envelope using SRK EoS. Output: 'bubble_T', 'bubble_P', 'dew_T', 'dew_P' (arrays), or 'cricondenbar_P/T', 'cricondentherm_P/T', 'critical_P/T' (scalars).
