lbs.SteadyStateSolver

Generalized implementation of a steady state solver. This solver calls the Across-Groupset (AGS) solver for the lbs-data block.

Example usage:

Create this object:

params = 
{
    param_name1 = value1,
    param_name2 = value2,
    --etc.
}
lbs.SteadyStateSolver.Create(params)

Required Input parameters

►lbs_solver_handle       Handle to an existing lbs solver

type=INTEGER. Handle to an existing lbs solver

Optional Input parameters

►dt       Desired initial timestep size

type=FLOAT. Desired initial timestep size.

Default value: 0.01(double)

Allowable values: >= 1e-12(double)

►end_time       Transient end-time if applicable

type=FLOAT. Transient end-time if applicable.

Default value: 1(double)

►max_time_steps       Maximum number of timesteps to allow

type=INTEGER. Maximum number of timesteps to allow. Negative values disables this.

Default value: -1

►name       A text name to associate with the solver

type=STRING. A text name to associate with the solver. This name will be used in status messages and verbose iterative convergence monitors.

Default value: "SteadyStateSolver"

►start_time       Transient start-time if applicable

type=FLOAT. Transient start-time if applicable.

Default value: 0(double)

►time       Current time of the solver

type=FLOAT. Current time of the solver.

Default value: 0(double)

►timestepper       Handle to a timestepper

type=INTEGER. Handle to a timestepper. If not supplied then a ConstantTimeStepper will be created.

Default value: 0
