Dune::CurvatureOperator< IGridView, IGridMapper, CL > Class Template Reference

Class defining an operator that assigns a curvature to each element or each vertex of the interface grid. The curvature is approximated by interpolation with a sphere (through the center points of an interface element and its neighbors). The enum CurvatureLayout determines whether the curvature is approximated at the vertices or elements of the grid. NOTE that the algorithm IN 3D might provide poor approximations for non-spherical interfaces and IN 3D the algorithm in general does not converge under grid refinement. More...

template<class Curvatures , class Centers , CurvatureLayout Layout = CL>

std::enable_if_t< Layout==Vertex, void > Dune::CurvatureOperator< IGridView, IGridMapper, CL >::operator() ( Curvatures &  curvatures, Centers &  centers  ) const

inline

Operator that assigns a curvature to each element or each vertex of the interface grid. The curvature is approximated by interpolation with a sphere (osculating circle/sphere through incident interface vertices).

Parameters

curvatures	A container to store the curvature of each element or each vertex of the interface grid
centers	A container to store the centers of curvatures (sphere center points) corresponding to the approximated curvature of each element or each vertex of the interface grid
