Constructor & Destructor Documentation

virtual itk::fem::Solution::~Solution ( )

virtual

Virtual destructor should properly destroy the object and clean up any memory allocated for matrix and vector storage.

Member Function Documentation

virtual Float itk::fem::Solution::GetSolutionValue ( unsigned int  i, unsigned int  solutionIndex = 0  ) const

pure virtual

Returns value of i-th element in a solution vector. This value is calculated generalized displacement of the i-th degree of freedom in a FEM problem. Note that in general there may be several solution vectors. You can select which one do you want by passing the second parameter.

Parameters

i	element index in solution vector
solutionIndex	index of solution vector to get value from

Note

If the solution vector doesn't exist (problem was not yet solved), or the index i is out of range, the function returns 0.0.

Implemented in itk::fem::LinearSystemWrapperItpack, itk::fem::LinearSystemWrapperVNL, and itk::fem::LinearSystemWrapperDenseVNL.

Referenced by itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >::GetSolution(), and itk::fem::ImageMetricLoad< TMoving, TFixed >::GetSolution().
