uniformTotalPressure

Description

The uniformTotalPressure is a boundary condition that provides provides a time-varying form of the uniform total pressure boundary condition totalPressure.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            uniformTotalPressure;
    p0              <Function1<scalar>>;

    // Optional entries
    U               <word>;
    psi             <word>;
    rho             <word>;
    phi             <word>;

    // Conditional entries

        // if 'psi' is not 'none'
        gamma       <scalar>;

    // Inherited entries;
    ...
}
