Detailed Description

This boundary condition provides a supersonic free-stream condition.

- supersonic outflow is vented according to ???

supersonic inflow is assumed to occur according to the Prandtl-Meyer expansion process.
subsonic outflow is applied via a zero-gradient condition from inside the domain.

Usage

Property	Description	Required	Default value
`T`	Temperature field name	no	T
`p`	Pressure field name	no	p
`psi`	Compressibility field name	no	thermo:psi
`UInf`	free-stream velocity	yes
`pInf`	free-stream pressure	yes
`TInf`	free-stream temperature	yes
`gamma`	heat capacity ratio (cp/Cv)	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            supersonicFreestream;
        UInf            500;
        pInf            1e4;
        TInf            265;
        gamma           1.4;
    }

Note: This boundary condition is ill-posed if the free-stream flow is normal to the boundary.
