Xinya,
Take a look at the example
$PETSC_DIR/src/snes/examples/tutorials/network/pflow/pf.c This example
models power grid steady-state equations (power flow) using DMNetwork.

Shri,
Thank you for your suggestion.
In the code, DMDACreat1D was used to create distributed array to manage
parallel grid and vectors:
DMDACreate1d(PETSC_COMM_WORLD, DM_BOUNDARY_NONE, 4*ngen, 1, 1, NULL, da);
How to use DMPlex/DMnetwork instead of DMDA? Which function should I call?
Thanks

If you know the near null space then you should also always set it
