[petsc-users] interchange between two different DMDAs

[Kun Jiao]

Hi,

I have a problem that need to interchange between two different DMDAs. They have the exactly same size, however they are distributed/partitioned differently across multiple processes. For instance, one DMDA is created with DMDACreated1d, the other is created with DMDACreated3d. How can I interchange between different DMDAs with VecScatter, or something else?

Regards,
Kun
