Hi Dmitry, I am using the DM solver to solve a Cahn Hilliard equation using a C0 discretization. I would like to use the preconditioner used in
http://www.mcs.anl.gov/~anitescu/Presentations/2011/anitescu-2011-SIAM-CSE-DVI.pdf I have been able to use the PETSC-DM solver with the VI solver to solve the Cahn Hilliard equation, but I haven’t been able to get a field-split preconditioner to work.
