OOF2: The Manual
Name
Uniform (BasicUniformDriver) — Take fixed, uniform time steps.
Synopsis
BasicUniformDriver
(stepsize
)
Details

Base class:
BasicStepDriver

Parameters:
stepsize
 Time step size. Type: A positive real number.
Description
Using BasicUniformDriver
as the
time_stepper
in BasicSolverMode tells OOF2 to solve a time
dependent problem using uniform stepping, in which all time steps
are the same size.
Uniform stepping requires less computation per step than adaptive stepping, but can be either much less accurate (if the step size is too large) or much less efficient (if the step size is too small).
BasicAdaptiveDriver
automatically uses the
SS22 method with
theta1
=theta2
=0.5
if the equations contain second order time derivatives.
It uses CrankNicolson otherwise.
