[Paraview] [EXT] Re: Stupid question on Programmable Source

[Dennis Conklin]

Utkarsh,

Well, I hate to be difficult, but I've got to play to my strengths  ;-)

In my routine if I:
1.  Do not declare any output (just accept the predefined output, which is set to vtkUnstructuredGrd).   Then your print statements work but my program kills Paraview with a segmentation fault

2.  If I declare an output with:
output=self.GetUnstructuredGridOutput()
Then my program succeeds and I get my mesh (just not many cell variables yet as I haven't figured out how to do that 97 times efficiently).  If I turn on your print statements it complains that there is no CellData available.

I have attached the script if there is anything obvious that I am doing incorrectly.

Thanks for your help

Dennis

Should work just fine for vtkUnstructuredGrid grid too. Are you creating the output yourself by any chance? You should be using the "output" variable predefined for you. e.g. attached state file works just fine for me with git/master, but I am sure it should work with 4.4.
