Hello dealiiers, I'd like to use the nice dealii framework of parallel computing with multiple processors using distributed memory, which is illustrated in step-40. It is clear that we can recover the solution on the processor owned cells as well as on a layer of ghost cells. My question is whether dealii has some functionalities to reconstruct the solution on the entire distributed triangulation, including artificial cells, or I have to explicitly exchange those information between processors. Any suggestion and hint is appreciated. Thank you very much.
Best regards, Xin
