Class
    Foam::totalPressureVelocityLagrangianVectorFieldSource
 
Description
    This source condition provides a velocity in a given direction with a
    magnitude calculated from the difference between a specified upstream
    pressure and the local interpolated pressure.
 
Usage
    \table
        Property  | Description                           | Required? | Default
        direction | The velocity direction                | yes       |
        p0        | The upstream total pressure           | yes       |
        pc        | The name of the carrier pressure field | no       | p
    \endtable
 
    Example specification:
    \verbatim
    <LagrangianModelName>
    {
        type            totalPressureVelocity;
        direction       (1 0 0);
        p0              1 [bar];
