Detailed Description

TimeStepper computes the solution of a given ODE. This is where the real work takes place (most of it takes place in the time slab or even in the local elements), whereas the responsibility of the ODE solver is also to solve the dual problem (using this class), compute stability factors and compute error estimates.

This class can be used in two different ways. One way is to call the static method solve() to solve a given ODE:

TimeStepper::solve(ode, u);

Alternatively, one can create a TimeStepper object and use this for repeatedly time stepping the ODE, one time slab at a time:

TimeStepper timeStepper(ode, u); timeStepper.step(); timeStepper.step();
