Disclaimer : This question is related to computational science, but it is a purely a post-processing question so if this is on the wrong board, please tell me
I would like to postprocess simulation results in an automatic way. Our current simulation software generates output in an ensight gold format. This means that for each simulation a name.case file is generated, which we can then open in paraview and post-process. However, the post-processing I have to carry out is very simple, yet will have to be done numerous time. Therefore, I want to carry it without launching the paraview gui in a fully automatic fashion.
What I am looking for is a way to launch a paraview script (maybe via pvpython?), do the rendering, output a .png and save it in the folder. All of this automatically without needed to launch a GUI or to interact with it. This aspect will eventually be residing inside a bash script.
I have tried looking into using pvpython which I could launch from the shell, but I have not found much documentation (is there any unified clear documentation on it?) on even opening ensight case files and post-processing images...
