<div dir="ltr"><div><div><div><div>Hi Matthieu,<br><br></div>That makes complete sense. I've thought about putting in a C++ Catalyst pipeline in the main source code that could be used to just write out the data at some prescribed file name and frequency but haven't forced myself to do it. It gets slightly more complicated when dealing with multiple inputs. In the Examples/Catalyst/SampleScripts subdirectory of the source code there are two Python scripts that can be used to write out the full grid, gridwriter.py and allinputsgridwriter.py. <br><br></div>If you create a C++ script to do that and want to have it added into ParaView, I can help with that. Otherwise, I'll get to it eventually...<br><br></div>Cheers,<br></div>Andy<br><div><div><div><br></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Sep 21, 2016 at 10:29 AM, Lokman Rahmani <span dir="ltr"><<a href="mailto:lokman.rahmani@irisa.fr" target="_blank">lokman.rahmani@irisa.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-family:times new roman,new york,times,serif;font-size:12pt;color:#000000"><div>Hi Matthieu!<br></div><div><br></div><div>I investigated the same question recently, here is what I found so far.<br></div><div><br></div><div>In Catalyst/CoProcessing the python script is used to create a vtk pipeline</div><div><br></div><div>---------<br></div><div>vtkNew<<wbr>vtkCPPythonScriptPipeline> pipeline; <wbr> <br>pipeline->Initialize(<wbr>scriptPath)</div><div>--------- <br></div><div><br></div><div>This pipeline will be passed to vtk processor that will do the CoPorcessing by executing the pipeline<br></div><div><br></div><div>------<br></div><div>vtkCPProcessor* Processor = vtkCPProcessor::New(); <wbr> <wbr> <br>Processor->Initialize(); </div><div>Processor->AddPipeline(<wbr>pipeline.GetPointer());</div><div>Processor->CcProcess(...)<br></div><div>------<br></div><div><br></div><div>checking the souce code of VtkCPProcessor (<a href="https://gitlab.kitware.com/paraview/paraview/blob/master/CoProcessing/Catalyst/vtkCPProcessor.h" target="_blank">https://gitlab.kitware.com/<wbr>paraview/paraview/blob/master/<wbr>CoProcessing/Catalyst/<wbr>vtkCPProcessor.h</a>)<br></div><div><br></div><div>----<br></div><div><div><br></div><div><pre style="overflow-y:hidden;overflow-x:auto;font-family:Menlo,'Liberation Mono',Consolas,'DejaVu Sans Mono','Ubuntu Mono','Courier New','andale mono','lucida console',monospace;font-size:13px!important;display:block;padding:10px;margin:0px;line-height:1.5!important;word-break:break-all;word-wrap:normal;color:#333333;border-left-width:1px;border-style:none none none solid;border-color:#f0f0f0;border-radius:0px;white-space:pre-wrap;font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;word-spacing:0px;background-color:#ffffff"><code style="font-family:Menlo,'Liberation Mono',Consolas,'DejaVu Sans Mono','Ubuntu Mono','Courier New','andale mono','lucida console',monospace;font-size:inherit;padding:0px;color:inherit;border-radius:0px;white-space:pre-wrap;word-wrap:normal;background-color:transparent"><span style="display:inline-block"> <span style="color:#999988;font-style:italic">/// Add in a pipeline that is externally configured.
