Hi Andy,
As you suggested in your previous mail, i used allinputsgridwriter.py
script to write all the available fields as multiblock dataset and i
created co-processing scripts using this dataset. Now, i could handle
multiple 3d fields but i have still problem in the combination of
contour and vector visualization. In this case, the code hangs in same
way that i mentioned in my initial mail.
So, to find the source of the problem i tried different pipelines and
check the co-processing,
1 - A pipeline with only Glyph filter. In this case, i set Gradients as
Vectors in Active Attributes section in the properties window. The
co-processing is working without any problem in this case.
2 - I used Calculator Filter to compute vector using u*iHat+v*jHat
equation along with Glyph to produce vector field visualization. In this
case, the pipeline is working without any error under co-processing.
3 - A visualization pipeline with an iso-surface which is colored by
different variable. It works also.
4 - The combination of step 2 and 3. In this case, i used same
visualization pipeline with 2 but in this case, i add a Contour filter
to create an iso-surface for a scalar 3d field (same as step 3). The
co-processing code hands with white screen and does not produce the output.
So, it seems that the combination of Contour and vector visualization
affects the co-processing. Anyway, do you have similar experience in
co-processing?

Hi Ufuk,
I would suggest testing out some of the Catalyst examples which are in
the source code under the Examples/Catalyst subdirectory. I would also
suggest creating Catalyst scripts from data sets generated through
Catalyst output instead of the NetCDF files. There are two example
scripts for this in Examples/Catalyst/SampleScripts that you can use
for this.
As for the grid names for the axes, this may be a bug in ParaView.
I'll look into that.
Best,
Andy

Hi,
I am using co-processing (Catalyst) and i have couple of issues
about the behavior of the co-processing module.
1 - If i send multiple 2d variable or single 3d variable to the
co-processor, my custom code is working without any problem and
produces desired output. On the other hand, the code hangs with
multiple 3d variable (it basically opens a square white window and
waits, see the attached screenshot). I have no idea about the
problem because the terminal does not produces any output. I could
install the ParaView in debug mode and it might help?
2 - The axis names (edited by Edit Axes Grid section in Properties
window) are not written to the produced png file when the
visualization pipeline is driven by co-processing but it looks
fine under ParaView.
3 - When i trying to use volume rendering (single 3d field) along
with co-processing, the code gives following error
ERROR: In
/opt/progs/paraview-5.0.0/src/VTK/Common/ExecutionModel/vtkCompositeDataPipeline.cxx,
line 171
vtkPVDataRepresentationPipeline (0x7fea05244010): Can not execute
simple alorithm without output ports
...
...
ERROR: In
/opt/progs/paraview-5.0.0/src/VTK/Filters/Parallel/vtkPKdTree.cxx,
line 296
vtkPKdTree (0x7fea04f42840): (process 0) NumberOfDatasets = 0,
cannot determine volume bounds.
I could produce iso-surface with same code without any problem.
The volume rendering is also working under ParaView.
The last question might be related with the grid definition in the
co-processing because i am using single netcdf dataset to create
visualization scripts (python) under ParaView but in the model
code (co-processing) the dataset is defined as MultiBlockDataSet
due to the parallel nature of the simulation code.
