Detailed Description

Integrate an initial value problem using 4th.

Date:

2001/11/13 14:09:30

Revision:

1.8

order Runge-Kutta method.

This is a concrete sub-class of vtkInitialValueProblemSolver. It uses a 4th order Runge-Kutta method to obtain the values of a set of functions at the next time step.

Member Function Documentation

virtual const char* vtkRungeKutta4::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 vtkRungeKutta4::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 vtkRungeKutta4::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.

vtkRungeKutta4* vtkRungeKutta4::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.

virtual void vtkRungeKutta4::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkInitialValueProblemSolver.

vtkRungeKutta4* vtkRungeKutta4::New (    )  [static]

Construct a vtkRungeKutta4 with no initial FunctionSet. Reimplemented from vtkObject. Referenced by MakeObject().

virtual float vtkRungeKutta4::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 81 of file vtkRungeKutta4.h.

virtual float vtkRungeKutta4::ComputeNextStep (  float *    xprev, float *    dxprev, float *    xnext, float    t, float    delT )  [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.

virtual vtkInitialValueProblemSolver* vtkRungeKutta4::MakeObject (    )  [inline, virtual]

Create concrete instance of this object. Reimplemented from vtkInitialValueProblemSolver. Definition at line 92 of file vtkRungeKutta4.h.

virtual void vtkRungeKutta4::Initialize (    )  [protected, virtual]

Reimplemented from vtkInitialValueProblemSolver.
