Natural element method
The natural element method (NEM) 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. Applications. When the simulation is dynamic, this method prevents the elements to be ill-formed, having the possibility to easily redefine them at each time step depending on the geometry.
