[petsc-users] Segmentation violation in DMSwarmMigrate(sdm_, PETSC_TRUE)

[prateekgupta1709 at gmail.com]

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
