chi_physics.ConstantTimeStepper

Timestep controller that does not dynamically change.

Example usage:

Create this object:

params = 
{
    param_name1 = value1,
    param_name2 = value2,
    --etc.
}
chi_physics.ConstantTimeStepper.Create(params)

Optional Input parameters

►dt       Initial timestep to use

type=FLOAT. Initial timestep to use

Default value: 0.01(double)

►dt_min       Minimum allowable timestep

type=FLOAT. Minimum allowable timestep.

Default value: 1e-05(double)

►end_time       End time

type=FLOAT. End time
