Classes

LinearLUSolver([tolerance, criterion, ...])

The LinearLUSolver is an interface to the LU preconditioner in PETSc.

class fipy.solvers.petsc.linearLUSolver.LinearLUSolver(tolerance='default', criterion='default', iterations=10, precon=None)

Bases: PETScSolver

The LinearLUSolver is an interface to the LU preconditioner in PETSc. A direct solve is performed.

Parameters:

• tolerance (float) – Required error tolerance.

• criterion ({'default', 'unscaled', 'RHS', 'matrix', 'initial', 'legacy'}) – Interpretation of tolerance. See Convergence for more information.

• iterations (int) – Maximum number of iterative steps to perform.

• precon – ignored

DEFAULT_ITERATIONS = 1000

Default maximum number of iterative steps to perform

DEFAULT_PRECONDITIONER = None

Default preconditioner to apply to the matrix

DEFAULT_TOLERANCE = 1e-05

Default tolerance for linear solves unless criterion=”legacy”

LEGACY_TOLERANCE = 1e-10

Default tolerance for linear solves if criterion=”legacy”

__repr__()

Return repr(self).

property default_tolerance

Default tolerance for linear solve
