fipy.solvers.petsc.preconditioners

class fipy.solvers.petsc.preconditioners.DefaultPreconditioner

Bases: PETScPreconditioner

Apply PETSc’s default preconditioning to PETScSolver.

“The default preconditioner for sparse matrices is PCILU or PCICC with 0 fill on one process and block Jacobi (PCBJACOBI) with PCILU or PCICC in parallel.” [1]
