Natural element method

The natural element method is a meshless method to solve partial differential equation, where the elements do not have a predefined shape as in the finite [element method], but depend on the geometry.
A Voronoi diagram partitioning the space is used to create each of these elements.
Natural neighbor interpolation functions are then used to model the unknown function within each element.
