Actually, the partition-of-unity idea is only one part of the X-FEM. The X-FEM was the first to introduce the concept of introducing geometric features, such as cracks or voids, that are not explicitly meshed. This idea is combined with the PUM to form X-FEM. That is why the X-FEM has become so popular. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/134.253.26.6|134.253.26.6]] ([[User talk:134.253.26.6|talk]]) 00:14, 14 January 2009 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

== Why extended? ==

The article doesn't explain in much detail how this method differs from standard finite elements. Is it just standard finite elements with a certain class of discontinuous or non-smooth basis functions, or is there more to it than that? —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 22:54, 6 July 2013 (UTC)
