[petsc-dev] [petsc-users] Error running DMPlex example

[Gautam Bisht]

Hi Matt,

During the last week discussion with Mark, it became obvious that to add
PETSc's AMR capability in PFLOTRAN would require incorporation of DMPlex.

Currently, PFLOTRAN has multiple `modes` which include:
- RICHARDS: Single phase mass conservation,
-TH: Single phase mass + energy conservation,
-GENERAL: Two phase mass + energy conservation, etc.

All the different modes have portions of duplicate code for
Residual/Jacobian evaluation. I believe incorporation of DMComposite would
possibly shrink the current PFLOTRAN code.

Thus, I was curious to check if an example for DMPlex+DMComposite exists.

-Gautam.
