Hello, I am using the DMSwarm library in some Eulerian-Lagrangian approach to have vapor bubbles in water. I would like the bubbles to have an impact on the water fields of the same cells and the adjacent ones. Is there any petsc function that can allow to sum the ghost cell values (of an adjacent proc) to the actual ones (on the actual proc)?
Thanks a lot for your help. Best regards, Joauma
