Detailed Description

This boundary condition provides a time-varying form of the uniform total pressure boundary condition.


Patch usage

Property Description Required Default value
U velocity field name no U
phi flux field name no phi
rho density field name no none
psi compressibility field name no none
gamma ratio of specific heats (Cp/Cv) yes
pressure total pressure as a function of time yes

Example of the boundary condition specification:

    myPatch
    {
        type            uniformTotalPressure;
        U               U;
        phi             phi;
        rho             rho;
        psi             psi;
        gamma           1.4;
        pressure        uniform 1e5;
    }

The pressure entry is specified as a DataEntry type, able to describe time varying functions.

Note
The default boundary behaviour is for subsonic, incompressible flow.
