Natural element method
From Wikipedia, the free encyclopedia
The natural element method (NEM)[1][2][3] 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.[4][5][6]

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.
