Hi, I am writing a basic particle tracking code with an existing periodic DMDA. All velocity calculations and position updates work fine but migration throws segfault. I have checked and particles are within the periodic box as well.
I discovered that there is an internal field for coordinates which has to be defined using its identifier instead of explicitly registering a field. I am not registering any velocity field (using external vectors). Is there something I am missing? Thanks, Prateek
