I also noticed that in Catalyst (look at my last message here :
I have a vtk HDF writer in which I tested adding a second connection in
Port 0, but with 2 connections,
vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEP doesn't contain an
epoch anymore but incremental reals in both connections (2 filters output).
So, if someone can give us an explanation and a fix that would be great
? I wish there's a good resource explaining and demystifying VTK
