I have a question about the usage of periodic DA. 1) In function DACreate2d( ), there is an argument about DAPeriodicType. I assume the mentioned periodicity is for the global array, not for local grid?
2) If I use the periodic type for DA, together with SNES to solve a system, when I implement the FormFunctionLocal, I need to explicitly implement the boundary conditions? Or does DA periodic type has some built-in functionality? Thanks, Jianing
