<p>Hi Ufuk,</p>
<p>Good. You get the same result as me. I think the error messages start after the timestep loop has finished. The good news is that Paraview handles the termination of the client without crashing.</p>
<p>Can you find out how to get Paraview to render each timestep? </p>
<p>I guess to implement this in our simulations we'll have to put a 'system("paraview --script=something") ; in our code just after the FEAdaptor::Initialize() call. The script would connect Catalyst.</p>
<p>Cheers</p>
<p> </p>

<div class="moz-cite-prefix">Hi Peter,<br /> <br /> I followed your steps in Paraview 4.2 (compiled under MacOS 10.10.3) and as you mentioned, i could see the pipeline in the pipeline browser. I also decrease to time step (from 100 to 3) to test the code. After finishing the time step loop the ParaView gives following error,<br /> <!-- meta ignored --><br /> ERROR: In /Users/turuncu/Qsync/progs/paraview-4.2.0/src/VTK/Parallel/Core/vtkSocketCommunicator.cxx, line 735,vtkSocketCommunicator (0x7fd4837cd120): Could not send tag.<br /> <br /> ERROR: In /Users/turuncu/Qsync/progs/paraview-4.2.0/src/VTK/Parallel/Core/vtkSocketCommunicator.cxx, line 812,vtkSocketCommunicator (0x7fd4837cd120): Could not receive tag. 8013<br /> <br /> ERROR: In /Users/turuncu/Qsync/progs/paraview-4.2.0/src/VTK/Parallel/Core/vtkSocketCommunicator.cxx, line 812,vtkSocketCommunicator (0x7fd4837cd120): Could not receive tag. 1<br /> <br /> ERROR: In /Users/turuncu/Qsync/progs/paraview-4.2.0/src/VTK/Parallel/Core/vtkSocketCommunicator.cxx, line 812,vtkSocketCommunicator (0x7fd483a02280): Could not receive tag. 1<br /> <br /> In this case, the code is also compiled with ParaView 4.2.

<p>Hello,</p>
<p>I've made some progress, but its not the complete answer.</p>
<p>To make the Catalyst examples display in Paraview, you have to go Paraview>Catalyst>Connect AFTER the client has initialized Catalyst.<br /> You also have to turn OFF the file write in the catalyst script.</p>
<p>Try the following changes (I tested CxxFullExample)</p>
<p>1) In FEDriver.cxx, after the call to FEAdaptor::Initialize() , add something like</p>
<p> std::cout<<"Please connect in Paraview"<<endl;</p>
<p>sleep(20);</p>
<p>I also put a 'sleep(1)' into the timestep loop to give more time to manipulate paraview.</p>
<p>2) In feslicescript.py, you remove the calls to coprocessor.CreateWriter and change EnableLiveVisualization to True).</p>
<p>Now, the test sequence is:</p>
<p>1) start Paraview. DONT connect Catalyst.</p>
<p>2) run the CxxFullExample with (path)feslicecinema.py as argument .( To find out the exact command, go ctest --verbose)</p>
<p>3) When you see "Please connect in Paraview", in the Catalyst menu you go 'Connect' and dismiss the dialogs which follow.</p>
<p>You'll see some changes in the pipeline browser. Paraview can see some data but doesnt render it until after the end of the timestepping. Would you like to look at that?</p>
<p> </p>
<p>Cheers</p>

<p>Thanks for replying. Take a look at</p>

<p>Briefly,</p>
<p>Paraview segfaults with the above error message when I run any of the tests in ParaViewCatalystExampleCode-master with <em>coprocessor.EnableLiveVisualization(True). </em>They all pass when this flag is False. I've tested with V4.3.1 and with yesterday's development version. There's another user - <strong>u.utku.turuncoglu at be.itu.edu.tr</strong> <a title="[Paraview]
pqPipelineSource::getOutputPort( 0 ). Available number of
output ports: 0" href="mailto:paraview%40paraview.org?Subject=Re%3A%20%5BParaview%5D%20pqPipelineSource%3A%3AgetOutputPort%28%200%20%29.%20Available%0A%20number%20of%20output%20ports%3A%200&In-Reply-To=%3C60384.88.235.36.106.1433760302.squirrel%40webmail.be.itu.edu.tr%3E">u.utku.turuncoglu at be.itu.edu.tr </a>who has a similar problem on a different O/S.</p>
<p>Are the tests in ParaViewCatalystExampleCode-master known to run OK with <em>coprocessor.EnableLiveVisualization(True)? </em> Or is that not the only change needed to make these clients connect?</p>
<p>If we are running ParaViewCatalystExampleCode-master correctly we'd appreciate your advice on where to start looking for a bug.</p>
<p>best regards</p>

<p>Hello</p>
<p>I just built the current Paraview development version and got the same error on running the Catalyst examples.</p>
<p>Paraview declined the connection gracefully when the client was built with a different VTK version, so I suspect the issue isnt related to the socket handshake, but rather that it only occurs after the socket connection is successful. </p>
