Unfortunately I do not think that version is available which is why I was not using a script exported from Paraview gui with a .pvtu file open in it. Attempting to open vtk files generated in MPAS-O in the paraview GUI results in paraview not knowing which reader to use and crashing. John Patchett contacted kitware about this issue a few weeks ago; but again the build for version 4.3.2 that could open the output Vtk files is no longer up on the paraview site. I will attempt to follow your instructions and find out nonetheless, to be clear I should: 1. Use your script and write out a vtk file from MPAS-O 2. Open that file in the Paraview gui 3. Make the changes I want and export that change to a python script via coprocessing Is this correct?

When making the scripts in the GUI you'll want to use the same version of ParaView though that is linked with MPAS to make sure the generated Python scripts are compatible.

Did you get a chance to look through the Catalyst User's Guide? For MPAS, the names of the adaptor outputs are: 'X_Y_NLAYER-primal', 'X_Y_NLAYER-dual', 'X_Y_Z_1LAYER-primal', 'X_Y_Z_1LAYER-dual', 'X_Y_Z_NLAYER-primal', 'X_Y_Z_NLAYER-dual', 'LON_LAT_1LAYER-primal', 'LON_LAT_1LAYER-dual', 'LON_LAT_NLAYER-primal', 'LON_LAT_NLAYER-dual' The files that you want are the ones provided by Catalyst and not the ones that MPAS natively writes out. The Catalyst files all should be written out with pvtu extensions (e.g. X_Y_NLAYER-primal_1.pvtu). The MPAS native output is the .nc file. The other error that you're getting is that you have an active Python trace when going through the Catalyst export wizard and that trace needs to be stopped.

I took that file and opened it in the Paraview desktop gui. In paraview with coprocessing enabled (Tools > Plugin Manager > under catalyst option, hit load), I made the adjustment to the vertical level and then exported the state (CoProcessing > Export State). I do not get a python script as an output, I get the error "Cannot generate Python state when tracing is active." RuntimeError: Cannot generate Python state when tracing is active.

The way to get around this is to run Catalyst with a sample Python script that outputs the full data set that the adaptor provides. For MPAS this is slightly more complex because it provides several outputs, 10 in fact, depending on how the scientists want the data (e.g. spherical vs. projected, primal vs. dual grid, single level vs. multiple levels) for what they're trying to do. The attached script can be used to write out all 10 of these outputs which is done every 5th output (this can be changed by changing the outputfrequency value). The general workflow would be to run MPAS with this script for a small amount of time steps (maybe also with a smaller input data set). Then use those outputs to generate the Catalyst script that you want from the GUI. If this is a bit unclear, I'd recommend going through the Catalyst User's Guide (http://www.paraview.org/files/catalyst/docs/ParaViewCatalystUsersGuide_v2.pdf) for more details.

He'll get back to you soon with a detailed explanation and hints about how to get what you want done. Meanwhile, what is tripping us up is that MPAS's catalyst adaptor is not the same thing as ParaViews MPAS reader. The reader has the SetVerticalLevel(int) method, but the adaptor probably has an entirely different method for doing that. I don't know firsthand what that method is so we'll have to wait for his response. David E DeMarle Kitware, Inc.
