Detailed Description

Integrate a set of ordinary.

Date:

2001/11/13 14:09:26

Revision:

1.7

differential equations (initial value problem) in time.

Given a vtkFunctionSet which returns dF_i(x_j, t)/dt given x_j and t, vtkInitialValueProblemSolver computes the value of F_i at t+deltat.

Warning:

vtkInitialValueProblemSolver and it's subclasses are not thread-safe. You should create a new integrator for each thread.

Member Function Documentation

virtual const char* vtkInitialValueProblemSolver::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 vtkObject. Reimplemented in vtkRungeKutta2, and vtkRungeKutta4.

int vtkInitialValueProblemSolver::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 vtkObject. Reimplemented in vtkRungeKutta2, and vtkRungeKutta4.

virtual int vtkInitialValueProblemSolver::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 vtkObject. Reimplemented in vtkRungeKutta2, and vtkRungeKutta4.

vtkInitialValueProblemSolver* vtkInitialValueProblemSolver::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 vtkObject. Reimplemented in vtkRungeKutta2, and vtkRungeKutta4.

virtual void vtkInitialValueProblemSolver::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 vtkObject. Reimplemented in vtkRungeKutta4.

virtual float vtkInitialValueProblemSolver::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 in vtkRungeKutta2, and vtkRungeKutta4. Definition at line 75 of file vtkInitialValueProblemSolver.h. Referenced by vtkRungeKutta4::ComputeNextStep(), and vtkRungeKutta2::ComputeNextStep().

virtual float vtkInitialValueProblemSolver::ComputeNextStep (  float *    xprev, float *    dxprev, float *    xnext, float    t, float    delT )  [pure 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 in vtkRungeKutta2, and vtkRungeKutta4.

virtual vtkInitialValueProblemSolver* vtkInitialValueProblemSolver::MakeObject (    )  [pure virtual]

Create concrete instance of the object. Reimplemented in vtkRungeKutta2, and vtkRungeKutta4.

virtual void vtkInitialValueProblemSolver::SetFunctionSet (  vtkFunctionSet *    functionset )  [virtual]

Set / get the dataset used for the implicit function evaluation.

virtual vtkFunctionSet* vtkInitialValueProblemSolver::GetFunctionSet (    )  [virtual]

Set / get the dataset used for the implicit function evaluation.

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

Reimplemented in vtkRungeKutta4.
