static void Opm::H2OAirFluidSystem< Scalar, H2Otype >::init | ( |  | ) |

static bool Opm::H2OAirFluidSystem< Scalar, H2Otype >::isCompressible | ( | unsigned | phaseIdx | ) |

inline static

Returns true if and only if a fluid phase is assumed to be compressible.

## isIdealGas()

template<class Scalar , class H2Otype = TabulatedComponent<Scalar, H2O<Scalar> >>

static bool Opm::H2OAirFluidSystem< Scalar, H2Otype >::isIdealGas | ( | unsigned | phaseIdx | ) |

template<class Scalar , class H2Otype = TabulatedComponent<Scalar, H2O<Scalar> >>

static bool Opm::H2OAirFluidSystem< Scalar, H2Otype >::isIdealMixture | ( | unsigned |  | ) |

inline static

Returns true if and only if a fluid phase is assumed to be an ideal mixture.

We define an ideal mixture as a fluid phase where the fugacity coefficients of all components times the pressure of the phase are independent on the fluid composition. This assumption is true if Henry's law and Rault's law apply. If you are unsure what this function should return, it is safe to return false. The only damage done will be (slightly) increased computation times in some cases.
