Class
    Foam::codedFixedValuePointPatchField
 
Description
    Constructs on-the-fly a new boundary condition (derived from
    fixedValuePointPatchField) which is then used to evaluate.
 
    The \c value entry (optional) is used for the initial values.
    Otherwise the code is executed.
 
    The code entries:
    \plaintable
       codeInclude | include files
       codeOptions | compiler line: added to EXE_INC (Make/options)
       codeLibs    | linker line: added to LIB_LIBS (Make/options)
       localCode   | c++; local static functions
       code        | c++; patch value assignment
       codeContext | additional dictionary context for the code
    \endplaintable
 
    Example:
    \verbatim
    movingWall
    {
        type    codedFixedValue;
        value   uniform 0;
        name    rampedFixedValue;   // name of generated bc
 
        code
        #{
            operator==
            (
                vector(0,0,1) * min(10, 0.1*this->db().time().value())
            );
        #};
 
        codeContext
        {
             ...
        }
 
        //codeInclude
        //#{
        //    #include "fvCFD.H"
        //#};
 
        //codeOptions
        //#{
        //    -I$(LIB_SRC)/finiteVolume/lnInclude
        //#};
    }
    \endverbatim
 
    A special form is if the \c code section is not supplied. In this case
    the code gets read from a (runTimeModifiable!) dictionary system/codeDict
    which would have a corresponding entry
 
    \verbatim
    rampedFixedValue
    {
        code
        #{
            operator==(min(10, 0.1*this->db().time().value()));
        #};
    }
    \endverbatim
 
Note
    The code context dictionary can be supplied separately as the
    \c codeContext entry.
