[petsc-users] multiblock question

[Shao-Ching Huang]

Hi

We are planning a new (finite volume) multiblock code, in which each
block has logically structured mesh. We plan to create one DMDA for
one block (which could span across 1 or more processes; we already
have code). What would be the recommended PETSc-way to couple these
blocks together for implicit solves? We also need ghosted region
between two connected blocks (just like the ghost regions among the
subdomains within a DMDA) for interpolation.

Thanks.
