<p class="MsoNormal"><span lang="EN-GB">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">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:<o:p></o:p></span></p>
