I am using a post process script executed in the HPC of my institution for generating the streaklines of my simulation carried out in a multiblock mesh. I am calling the pvbatch as :
mpiexec -np 6 pvbatch --force-offscreen-rendering $my_script.py
When I run this locally on my laptop (for a small amount of timesteps) it works completely fine but I have been doing some tests on the HPC and as you can see in the attached screenshot, there are missing blocks in the rendering. It is worth to mention that they appear and dissappear and it is not always the same blocks that do that. It doesn’t seem a problem of the particle tracer filter because it tracks the particles motion successfully. It is my first time using this kind of post-process technique so I am not very experienced with this kind of errors when there is not a critical failure in the script.
Thanks in advance!
