Though DEM is very closely related to molecular dynamics, the method is generally distinguished by its inclusion of rotational degrees</ins>-<ins style="font-weight: bold; text-decoration: none;">of</ins>-<ins style="font-weight: bold; text-decoration: none;">freedom as well as stateful contact and often complicated geometries (including polyhedra). With advances in computing power and numerical algorithms for nearest neighbor sorting, it has become possible to numerically simulate millions of particles on a single processor. Today DEM is becoming widely accepted as an effective method of addressing engineering problems in granular and discontinuous materials, especially in granular flows, powder mechanics, and rock mechanics.</ins></div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">* Only edit this page if you can improve </del>the <del style="font-weight: bold; text-decoration: none;">content</del>.</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">* Improper use </del>of <del style="font-weight: bold; text-decoration: none;">this page will lead </del>to <del style="font-weight: bold; text-decoration: none;">permanent banning</del>.</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">Discrete element methods are relatively computationally intensive, which limits either the length of a simulation or </ins>the <ins style="font-weight: bold; text-decoration: none;">number of particles</ins>. <ins style="font-weight: bold; text-decoration: none;">Several DEM codes, as do molecular dynamics codes, take advantage </ins>of <ins style="font-weight: bold; text-decoration: none;">parallel processing capabilities </ins>to <ins style="font-weight: bold; text-decoration: none;">scale up the number of particles or length of the simulation</ins>. <ins style="font-weight: bold; text-decoration: none;">An alternative to treating all particles separately is to average </ins>the <ins style="font-weight: bold; text-decoration: none;">physics across many particles and thereby treat </ins>the <ins style="font-weight: bold; text-decoration: none;">material as a continuum</ins>. <ins style="font-weight: bold; text-decoration: none;">In </ins>the <ins style="font-weight: bold; text-decoration: none;">case of solid</ins>-<ins style="font-weight: bold; text-decoration: none;">like granular behavior as in soil mechanics, the continuum approach usually treats the material as elastic or elasto</ins>-<ins style="font-weight: bold; text-decoration: none;">plastic and models it with the finite element method or a mesh free method.
