[Paraview] filename_%t is not expanded to current time in Catalyst

[SeongMo]

Hi,

I wrote a OpenFOAM adaptor for Catalyst.

In the ParaView, the connection is made good and shows filtered flow 
field as written in the python script.

However, filename_%t and image_%t is not expanded as time marching but 
just write filename_0 and image_0.png.

As far as I know, %t should be replaced with current time as given in 
dataDescription->SetTimeData.

Any help would be appreciated.


snippet of my OpenFOAM Adaptor code for Catalyst is as follows:

// icoFoam.C

#ifdef USE_CATALYST
     Foam::HashTable<string> options = args.options();
     IStringStream is(options["scriptList"]);
     wordList scriptList = readList<word>(is);
     OFAdaptor::Initialize(scriptList, mesh);
#endif
     while (runTime.loop())
     {
         runTime.write();
#ifdef USE_CATALYST
         OFAdaptor::CoProcess(mesh, runTime);
#endif
     }
#ifdef USE_CATALYST
     OFAdaptor::Finalize();
#endif


// OFAdaptor.C

void CoProcess(Foam::fvMesh& mesh, Foam::Time& runTime)
{
        vtkNew<vtkCPDataDescription> dataDescription;
        dataDescription->AddInput("input");
        dataDescription->SetTimeData(runTime.value(), 
runTime.deltaTValue());
        if (runTime.end())
        {
            // assume that we want to all the pipelines to execute
            // if it is the last time step
            dataDescription->ForceOutputOn();
        }
        if 
(Processor->RequestDataDescription(dataDescription.GetPointer()) != 0)
        {
            Foam::polyMesh::readUpdateState meshState = mesh.readUpdate();

            if(meshState != Foam::polyMesh::UNCHANGED)
            {
                BuildVTKGrid(mesh);
            }
            UpdateVTKAttributes(mesh);
dataDescription->GetInputDescriptionByName("input")->SetGrid(multiBlockDataSet);
            Processor->CoProcess(dataDescription.GetPointer());
        }
}
