Transform from vtkCONVERGEReader to PolyData.

Good morning,

I am trying to use the reader class vtkCONVERGECFDReader to some object that I can easily work with. I have managed to do so with only one file in the folder, but if a time series is located on my working folder, only one is being loaded all the time, although the file name changes.

Thanks for the help!
