I am trying to read an ASCII Tecplot file into Paraview (5.11). It has two zones, which both have the same name. It reads ok, but with ExtractBlocks (which now uses block names, instead of indices like previously), when I select the zone I want, it outputs still both zones. This means that I am unable to extract the blocks I want. In the end, I would like to do this in python, so any solution that works with python will be perfect! Otherwise, I think it would be good if the TecplotReader could be modified such that unique block names will be available?
Thanks for the help. I tried Connectivity, but it needs a vtkDataSet. So I tried to MergeBlocks (is that the one to convert it to vtkDataSet?) before and then apply Connectivity, but that did not work.
Attached, you find an very simple example of the problem: one Tecplot file and the python script to read it into Paraview illustrating the problem. It also contains the MergeBlocks and Connectivity filters for your convenience.
