[Paraview] Paraview Live Visualisation C++ Pipeline

Hi Andy,
Could you please tell me, which data set you need ?Because it´s big data.
I´m doing (Ensight 6) format.
Greetings.

 Hi,

Can you share a data set that you are having an issue with?

Hi,
I apologize,I didn´t explain it well.

I´m using: Paraview 5.2.0-RC1 , 64 bit.
All fields data are being read but not visualized, that is, I get only one color when I color the data with a specific field.However, when I use "find data" function, I can see the data.This happens only with: velocity & pressure.I´m working on several configurations & the same thing happens with all of them.

Is it a bug or VTK has been corrupted or something else ?
Thanks in advance.

 Maybe I didn't understand what you were trying to do. Can you be a bit more specific?

Hi Andy, 

Thanks for your reply.
I think you've mixed my question up with someone else´s.I still have the problem with data-visualization (data are read but not visualized).

 Hi,

Please keep the discussion on the mailing list so that anyone can participate (also, stuff gets lost in my Inbox too).

The ParaView Catalyst Users Guide at http://www.paraview.org/files/ catalyst/docs/ ParaViewCatalystUsersGuide_v2. pdf has information on how to use the Live functionality. It's in Section 2.3.

Best,
Andy

Hi, thanks a lot for the quick respons.At least now we know that there’s no point to keep on trying. I’ll try to build and install it myself then. Is there any previous thread where I can find out more about the simulation + catalyst linking to a parallel server? Best regards,Simon From: Andy Bauer [mailto:andy.bauer at kitware.com ]

Subject: Re: [Paraview] Paraview Live Visualisation C++ Pipeline Hi,Currently the Live functionality only works when ParaView is built with Python bindings. My suggestion would be to build ParaView yourself. That should be much easier than trying to put in a C++ pipeline that can deal with the Live functionality properly. As for building ParaView, you may want to look into using the ParaView Superbuild (https://gitlab.kitware.com/ paraview/paraview-superbuild/) which will also build all needed dependencies. The dependencies are probably all there though since you've said that ParaView is already installed there.I'm not sure the set up you're looking for but if you want to run with the simulation+Catalyst linking to a parallel pvserver on the cluster which then connects to a client, you may want to use ParaView master. The reason for this is that there was a bug that had all of the simulation+Catalyst nodes only being able to communicate with a single pvserver node (multiple pvserver processes though). If you only want to connect the simulation+Catalyst to the GUI client or pvserver processes on a single node then 5.2 should work fine for you.Best,Andy  On Thu, Jan 26, 2017 at 9:53 AM, Kohlhase, Simon <simon.kohlhase at tum.de> wrote:
Hi, for a University Project we’re trying to run Paraview Live Simulation on the local cluster-network. Unfortunately the network only has a Paraview version without python-binding installed, therefore we would like to run the LiveSimulation with a C++-coded Pipeline Skript. As far as we understood, to make it work we have to rewrite the following lines from the PythonPipeline Script to C++, which turns out to be quite challenging: coprocessor.UpdateProducers( datadescription)# Write output data, if appropriate.coprocessor.WriteData( datadescription);# Live Visualization, if enabled.coprocessor. DoLiveVisualization( datadescription, "localhost", 22222) We tried the following: //INITIALIZEvtkNew<vtkLiveInsituLink> link;vtkSMProxyManager* proxyManager;vtkSMSessionProxyManager* sessionProxyManager;link -> SetInsituPort(22222);link -> SetHostname("localhost");proxyManager = vtkSMProxyManager:: GetProxyManager();sessionProxyManager = proxyManager-> GetActiveSessionProxyManager() ;link -> Initialize( sessionProxyManager); // Initialize returns 1, therefore connection established properly //Then we tried to coprocess with the following code:vtkNew<vtkXMLPImageDataWriter> writer;writer->SetInputConnection( producer->GetOutputPort());vtkSMProxy* proxy = sessionProxyManager->NewProxy( "insitu_writer_parameters"," XMLPImageDataWriter");vtkSMInputProperty* property = (vtkSMInputProperty*) proxy -> GetProperty("Input"); //set input of proxy to our writer or datadescription – DOESN’T WORKwhile(true){  link->InsituUpdate( dataDescription->GetTime(), dataDescription->GetTimeStep() );  //update pipeline  link->InsituPostProcess( dataDescription->GetTime(), dataDescription->GetTimeStep() );  if(link->GetSimulationPaused() ){    if(link->WaitForLiveChange()){     break;    }  } else{    break;}  } So how are we supposed to get the data from our simulation into the Proxy?We have been trying and searching the documentation for the right functions, but we can’t figure out how to do it. We would really appreciate some help ;-) Best regards,Simon Kohlhase
