The cells are indeed created, and I believe they are as you expect.

You can "see" them in the data:
cout << "There are " << structuredGrid->GetNumberOfCells() << " cells." << endl;

But I'm not sure if there is a filter that will actually produce them.
I agree that this would often be very nice to see - does anyone know
if this already exists? Or should we write one?

Thanks,
