Natural element method
open-in-new
<p>The natural element method (NEM) is a <a href="/facts/Meshless_method/uUhEQD3K">meshless method</a> to solve <a href="/facts/Partial_differential_equation/DyPsBlv7">partial differential equation</a>, where the <i>elements</i> do not have a predefined shape as in the <a href="/facts/Finite_element_method/eUcfP1vn">finite element method</a>, but depend on the geometry. </p><p>A <a href="/facts/Voronoi_diagram/AhQY5LD8">Voronoi diagram</a> partitioning the space is used to create each of these elements. </p><p><a href="/facts/Natural_neighbor_interpolation/QSxn2NaR">Natural neighbor interpolation functions</a> are then used to model the unknown function within each element. </p>
