As a followup to my last reply, I’m pasting the script below for reference because there may be a problem within of which I am not aware. The script is not too clean, though.
Also attached is an image of the output where I see the vertical level still needs to be turned down.

Regarding the adding attributes error message, it is likely that the ActiveSource is not an MPAS reader at that point in time.
…GetActiveSource().__class__ should tell your what it is.
Regarding the level setting - what is yourReader.ShowMultilayerView?
The docs indicated a value of 1 makes VerticalLayer immaterial.

I’m one of the DSS interns working under Jim Ahrens for the summer. I am using paraviews python script in the HPC and I’m having an issue adjusting an attribute of paraview.simple.netcdfmpasreader “VerticalLevel”.
I want to adjust it from the default to one and attempted:
paraview.simple.NetCDFMPASreader.VerticalLevel = 1
paraview.simple.NetCDFMPASreader.VerticalLevel = ‘1'
And
paraview.simple.GetActiveSource().VerticalLevel = 1
The first two operate with no errors doing nothing in the program and the last returns an error that the class bars adding attributes to prevent errors due to spelling.
How do I adjust the vertical level setting?
Thank you in advance for your assistance.
