Okay that explains the issue I was facing.Â
I wanted to understand how the ID were assigned because I was having some issues with the postprocessing of data.Â
I found out that if I pause and restart a simulation the ID change, but now I understand it is because of the repartition, as I am using several CPUs to solve my simulation.
I was using the IDs as they are unique, but now I solved the issue in my postprocessing by taking the coordinates into consideration instead. However, if there is a logical assignment of IDs why does it change with the repartition?
