Hi,


I use OpenFOAM-2.4.0-MNF to add a new usage option in my user defined utility based on vorticity. The make/options file of my utility is the same as the one of vorticity.
As the make/options file in vorticity has been linked to postCalc so I just go into postCalc.C and add Foam::argList::addOption
Here is part of the code in postCalc.C

int main(int argc, char *argv[])
{

    Foam::timeSelector::addOptions();
    #include "addRegionOption.H"
    Foam::argList::addBoolOption
    (
        "noWrite",
        "suppress writing results"
    );
    #include "addDictOption.H"
    Foam::argList::addOption
    (
        "fieldName",
        "name",
        "specify a fieldName for the velocity"
        "example: -fieldName N2"
    );
    #include "setRootCase.H"
    #include "createTime.H"
    Foam::instantList timeDirs = Foam::timeSelector::select0(runTime, args);
    #include "createNamedMesh.H"
    ...

Here is part of the code of my utility

#include "calc.H"
#include "fvc.H"
#include "argList.H"
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //


void Foam::calc(const argList& args, const Time& runTime, const fvMesh& mesh)
{   
    bool writeResults = !args.optionFound("noWrite");
    
    word fieldName;
    if (args.optionFound("fieldName"))
    {
        args.optionLookup("fieldName")() >> fieldName;
    }
    else
    {
        FatalErrorIn("vorticity::calc")
        << "fieldName option must be used with this tool"
        << nl
        << exit(FatalError);
    }

The utility and postCalc.C are all compiled successfully but when I use it, it shows:
--> FOAM FATAL ERROR:
Invalid option: -fieldName

I also put argList::addOption part into my utility but it still does not work

What did I miss? Can anyone help me please?


Thanks in advance.
