[Paraview] Tensor transpose for lambda 2

I'm doing some fluid flow visualizations, and I'm trying to compute the lambda_2 scalar field (which is the second eigenvalue of a tensor based on the velocity gradient). It seems like the python calculator has NEARLY everything I need (eigenvalue, gradient) but I also need to be able to take the t

[Paraview] Update data after timestep is taken

Hi, I have a Python script that opens an ENSIGHT data file that contains cell data for several timesteps. I'd like to be able to perform an operation on one timestep and then advance to the next timetstep. I have tried using the GoToNext() method on the animation scene like it shows when I d

Thanks Ben, I followed your instructions and the build was successful in release mode. However, when I run the executable it crashes on load. Attempting to debug this I tried to build in debug mode using the same approach. Unfortunately the debug build fails with an error, qtmain.lib(qtmain_win.

[Paraview] How to detect valid read in Programmable filter

All, I want to try to read some point arrays in the Programmable Filter and take action based on whether or not the arrays have been loaded into Paraview.I am pretty lost in the PF, so take that for what it's worth. If I try something like try: displ=block.PointData['DISPL'] Print di

Re: [Paraview] adjusting vertical level setting via paraview python script

I think the changes to the XML formats were done prior to PV 4.3.1 but am not certain. 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. On Mon, Aug 3, 2015 at 3:56 PM, Eatmon

Re: [Paraview] adjusting vertical level setting via paraview python script

Oh, my mistake I didn’t understand the instructions. I will run it again to get .pvtu output, however in my previous scripts that generate VTK output there was an issue where the currently released 4.3.1 version of Paraview could not open the files due to a back compatability issue. I had a deve

Re: [Paraview] adjusting vertical level setting via paraview python script

Hi, Please reply to everyone so that anyone that wants to follow along with the conversation can. 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-d

Re: [Paraview] Differences between OpenGL and OpenGL2 versions of ParaView

Hi Joachim, Do you want me to send in a bug report for these problems? I assume there's no work-around that I can do to make things work. Using OpenGL2 is quite a bit faster, so I'm hoping a fix can come out soon. Thanks! -- Adam *--* *Adam L. Lyon* *Scientist; Associate Division Head for Sys

Re: [Paraview] adjusting vertical level setting via paraview python script

Hi, Dave is correct in that the reader's output needs to match what the adaptor is producing and in this case the MPAS NetCDF reader does not match what the adaptor provides to Catalyst. The way to get around this is to run Catalyst with a sample Python script that outputs the full data set that t

Re: [Paraview] adjusting vertical level setting via paraview python script

Andy Bauer just explained it to me. 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) metho

Hello. Thanks for solution. I tried ExtractBlock filter and it works OK (I able to use Calculator and IntegrateVariables then) but only for volume (Fluid Domain in my case), not for boundaries.
