Constructor & Destructor Documentation

AdaptiveSolve::AdaptiveSolve	(	std::function< int(double)>	doStepFunction,
		std::function< void(double)>	postProcessFunction = [](double) {}
	)

ctor

Parameters

doStepFunction	function that solves a problem for a given t and returns the number of iterations required. -1 indicates a failed solve
postProcessFunction	function that is called with the current time

Member Function Documentation

void AdaptiveSolve::Solve	(	double	tEnd,
		double	tStart = 0
	)

Perform an adaptive time integration from t = tStart to t = tEnd.

One time step starts at time t and tries to apply the increment dt. If the step finishes without an exception, it is finalized by updating the time to t+dt calling the postprocess function. Only NoConvergence exception will be caught. They cause a decrease in the time step.

Parameters

tEnd	end time
tStart	start time

Remarks

tStart comes second (may be unintuitive) to default it to zero.
