Class
    Foam::rotatingTotalPressureFvPatchScalarField
 
Description
    This boundary condition provides a total pressure condition for patches
    in a rotating frame.
 
Usage

        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 |
        p0           | static pressure reference | yes       |
        origin       | origin of rotation in Cartesian co-ordinates | yes|
        axis         | axis of rotation        | yes         |
        omega        | angular velocity of the frame | no |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            rotatingTotalPressure;
        U               U;
        phi             phi;
        rho             rho;
        psi             psi;
        gamma           1.4;
        p0              uniform 1e5;
        origin          (0 0 0);
        axis            (0 0 1);
        omega           100 [rpm];
    }
    \endverbatim
 
    The \c omega entry is a Function1 of time, see Foam::Function1s.
