fipy.solvers.scipy.linearBicgstabSolver module

class fipy.solvers.scipy.linearBicgstabSolver.LinearBicgstabSolver

Bases: fipy.solvers.scipy.scipyKrylovSolver._ScipyKrylovSolver

The LinearBicgstabSolver is an interface to the Bicgstab solver in Scipy, with no preconditioning by default.

Parameters:
  • tolerance: The required error tolerance.
  • iterations: The maximum number of iterative steps to perform.
  • precon: Preconditioner to use.

fipy.solvers.scipy.linearCGSSolver module

class fipy.solvers.scipy.linearCGSSolver.LinearCGSSolver(tolerance=1e-15, iterations=2000, precon=None)

Bases: fipy.solvers.scipy.scipyKrylovSolver._ScipyKrylovSolver

The LinearCGSSolver is an interface to the CGS solver in Scipy, with no preconditioning by default.

Parameters:
  • tolerance: The required error tolerance.
  • iterations: The maximum number of iterative steps to perform.
  • precon: Preconditioner to use.

fipy.solvers.scipy.linearGMRESSolver module

class fipy.solvers.scipy.linearGMRESSolver.LinearGMRESSolver(tolerance=1e-15, iterations=2000, precon=None)

Bases: fipy.solvers.scipy.scipyKrylovSolver._ScipyKrylovSolver

The LinearGMRESSolver is an interface to the GMRES solver in Scipy, with no preconditioning by default.

Parameters:

fipy.solvers.scipy.linearLUSolver module

class fipy.solvers.scipy.linearLUSolver.LinearLUSolver(tolerance=1e-10, iterations=1000, precon=None)

Bases: fipy.solvers.scipy.scipySolver._ScipySolver

The LinearLUSolver solves a linear system of equations using LU-factorisation. The LinearLUSolver is a wrapper class for the the Scipy scipy.sparse.linalg.splu moduleq.

Create a Solver object.

Parameters:
  • tolerance: The required error tolerance.
  • iterations: The maximum number of iterative steps to perform.
  • precon: Preconditioner to use. This parameter is only available for Trilinos solvers.
