Class

Group
    grpCoupledBoundaryConditions
 
Description
    This boundary condition provides a temperatue interface to an external
    application.
 
    Values are transferred as plain text files, where OpenFOAM data are
    written as follows:
 
    \verbatim
        # Patch: <patch name>
        <magSf1> <value1> <qDot1> <htc1>
        <magSf2> <value2> <qDot2> <htc2>
        <magSf3> <value3> <qDot3> <htc2>
        ...
        <magSfN> <valueN> <qDotN> <htcN>
    \endverbatim
 
    and received as the constituent pieces of the `mixed' condition, i.e.
 
    \verbatim
        # Patch: <patch name>
        <value1> <gradient1> <valueFracion1>
        <value2> <gradient2> <valueFracion2>
        <value3> <gradient3> <valueFracion3>
        ...
        <valueN> <gradientN> <valueFracionN>
    \endverbatim
 
    Data is sent/received as a single file for all patches from the directory
 
    \verbatim
        $FOAM_CASE/<commsDir>
    \endverbatim
 
    At start-up, the boundary creates a lock file, i.e..
 
    \verbatim
        OpenFOAM.lock
    \endverbatim
 
    ... to signal the external source to wait.  During the boundary condition
    update, boundary values are written to file, e.g.
 
    \verbatim
        <fileName>.out
    \endverbatim
 
    The lock file is then removed, instructing the external source to take
    control of the program execution.  When ready, the external program
    should create the return values, e.g. to file
 
    \verbatim
        <fileName>.in
    \endverbatim
 
    ... and then reinstate the lock file.  The boundary condition will then
    read the return values, and pass program execution back to OpenFOAM.
 
    To be used in combination with the functionObjects::externalCoupled
    functionObject.
 
Usage
    \table
        Property | Description                              | Required | Default
        outputTemperature | Output temperature: fluid/wall  | yes |
        htcRefTemperature | Fluid temperature for htc: cell/user  | no | cell
        Tref     | Reference temperature [K] for htc        | conditional |
    \endtable
 
    The user-specified reference temperature Tref is specified as
    a Foam::Function1 of time but spatially uniform.
