SNESCOMPOSITE#

Builds a nonlinear solver/preconditioner by composing together several SNES nonlinear solvers [BKST15]

Options Database Keys#

  • -snes_composite_type <type: one of multiplicative, additive, additiveoptimal> - Sets composite preconditioner type

  • -snes_composite_sneses - <snes0,snes1,…> list of SNES to compose
