<div class="moz-cite-prefix">Hi Andy,<br>
<br>
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.<br>
<br>
So, to find the source of the problem i tried different pipelines
and check the co-processing,<br>
<br>
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.<br>
<br>
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.<br>
<br>
3 - A visualization pipeline with an iso-surface which is colored
by different variable. It works also.<br>
<br>
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.<br>
<br>
So, it seems that the combination of Contour and vector
visualization affects the co-processing. Anyway, do you have
similar experience in co-processing?<br>
<br>
Regards,<br>

<div>Hi Ufuk,<br>
<br>
</div>
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.<br>
<br>
</div>
As for the grid names for the axes, this may be a bug in
ParaView. I'll look into that.<br>

<br>
I am using co-processing (Catalyst) and i have couple of
issues about the behavior of the co-processing module.<br>
<br>
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?<br>
<br>
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.<br>
<br>
3 - When i trying to use volume rendering (single 3d field)
along with co-processing, the code gives following error<br>
<br>
ERROR: In
/opt/progs/paraview-5.0.0/src/VTK/Common/ExecutionModel/vtkCompositeDataPipeline.cxx,
line 171<br>
vtkPVDataRepresentationPipeline (0x7fea05244010): Can not
execute simple alorithm without output ports<br>
...<br>
...<br>
ERROR: In
/opt/progs/paraview-5.0.0/src/VTK/Filters/Parallel/vtkPKdTree.cxx,
line 296<br>
vtkPKdTree (0x7fea04f42840): (process 0) NumberOfDatasets =
0, cannot determine volume bounds.<br>
<br>
I could produce iso-surface with same code without any
problem. The volume rendering is also working under
ParaView.<br>
<br>
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.<br>
