vtkRungeKutta2 Class Reference
#include <vtkRungeKutta2.h>
Detailed Description
Integrate an initial value problem using 2nd order Runge-Kutta method.This is a concrete sub-class of vtkInitialValueProblemSolver. It uses a 2nd order Runge-Kutta method to obtain the values of a set of functions at the next time step.

| static int vtkRungeKutta2::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Given initial values, xprev , initial time, t and a requested time interval, delT calculate values of x at t+delT (xnext). delTActual is always equal to delT. Since this class can not provide an estimate for the error error is set to 0. maxStep, minStep and maxError are unused. This method returns an error code representing the nature of the failure: OutOfDomain = 1, NotInitialized = 2, UnexpectedValue = 3
