Revision:

1.4

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.

Member Function Documentation

virtual const char* vtkRungeKutta2::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkInitialValueProblemSolver.

int vtkRungeKutta2::IsTypeOf (  const char *    type )  [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. Reimplemented from vtkInitialValueProblemSolver.

virtual int vtkRungeKutta2::IsA (  const char *    type )  [virtual]

Return 1 if this class 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. Reimplemented from vtkInitialValueProblemSolver.

vtkRungeKutta2* vtkRungeKutta2::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkInitialValueProblemSolver.

vtkRungeKutta2* vtkRungeKutta2::New (    )  [static]

Construct a vtkRungeKutta2 with no initial FunctionSet. Reimplemented from vtkObject. Referenced by MakeObject().

virtual float vtkRungeKutta2::ComputeNextStep (  float *    xprev, float *    xnext, float    t, float    delT )  [inline, virtual]

Given initial values, xprev , initial time, t and time interval, delT calculate values of x at t+delT (xnext) It returns an estimated value for the error (not implemented yet) or -1 on failure (for example, if the integration moves out of a data set) Reimplemented from vtkInitialValueProblemSolver. Definition at line 72 of file vtkRungeKutta2.h.

virtual float vtkRungeKutta2::ComputeNextStep (  float *    xprev, float *    dxprev, float *    xnext, float    t, float    delT )  [virtual]

Reimplemented from vtkInitialValueProblemSolver.

virtual vtkInitialValueProblemSolver* vtkRungeKutta2::MakeObject (    )  [inline, virtual]

Create concrete instance of this object. Reimplemented from vtkInitialValueProblemSolver. Definition at line 81 of file vtkRungeKutta2.h.

void vtkRungeKutta2::operator= (  const vtkRungeKutta2 &    )  [inline, protected]

Definition at line 90 of file vtkRungeKutta2.h.
