Class
    Foam::codedFixedValueFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    Constructs on-the-fly a new boundary condition (derived from
    fixedValueFvPatchField) which is then used to evaluate.
 
Usage
    Example:
    \verbatim
    <patchName>
    {
        type    codedFixedValue;
        value   uniform 0;
        name    rampedFixedValue;   // name of generated BC
 
        code
        #{
            operator==(min(10, 0.1*this->db().time().value()));
        #};
 
        //codeInclude
        //#{
        //    #include "fvCFD.H"
        //#};
 
        //codeOptions
        //#{
        //    -I$(LIB_SRC)/finiteVolume/lnInclude
        //#};
    }
    \endverbatim
 
    A special form is if the 'code' section is not supplied. In this case
    the code is read from a (runTimeModifiable!) dictionary system/codeDict
    which would have a corresponding entry:
 
    \verbatim
    <patchName>
    {
        code
        #{
            operator==(min(10, 0.1*this->db().time().value()));
        #};
    }
    \endverbatim
