Class
    Foam::calculatedFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    This boundary condition is not designed to be evaluated; it is assmued
    that the value is assigned via field assignment, and not via a call to
    e.g. \c updateCoeffs or \c evaluate.
 
    \heading Patch usage
 
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            calculated;
        value           uniform (0 0 0);    // optional value entry
    }
    \endverbatim
