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.

ielement index in solution vector
solutionIndexindex of solution vector to get value from
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.
