Name
Basic (BasicSolverMode) — Let OOF2 choose many solution parameters.
Synopsis
BasicSolverMode(time_stepper,matrix_method)
Details
-
Base class:
SolverMode -
Parameters:
time_stepper- How to take time steps. Type: An object of the
BasicStepDriverclass. matrix_method- How to solve matrix equations. Type: An object of the
BasicMatrixMethodclass.
Description
When the solver_mode argument to OOF.Subproblem.Set_Solver is
BasicSolverMode, OOF2 makes all of the
detailed decisions about the solution method. The
user only has to choose whether the time stepper should be static, uniform, or
adaptive,
and whether the matrix method should be iterative or direct. The specific
time stepping method, matrix method, and nonlinear solver, if
required, are all selected automatically.
If the SubProblem is nonlinear,
BasicSolverMode will use Newton's method, with
relative_tolerance=10-5,
absolute_tolerance=10-15,
and maximum_iterations=200. The other details
depend on settings of time_stepper and
matrix_method.
