Detailed Description

This boundary condition provides a supersonic free-stream condition.

- supersonic outflow is vented according to ???


Patch usage

Property Description Required Default value
TName Temperature field name no T
pName Pressure field name no p
psiName 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:

    myPatch
    {
        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.
