&nbsp; Hi, I&#39;m trying to come up with a good translation to spanish of the term &quot;Envelope deformation&quot; but I can&#39;t find any information on why it is called like that.<br>&nbsp; Does it have anything to do with an envelope you use to send a letter (by snail mail)? Or maybe it has more to do with the verb &quot;envelope&quot; as in &quot;wrap around&quot; or &quot;surround&quot;. Maybe it&#39;s someone&#39;s name.<br>
<br>&nbsp; Any help appreciated,<br>&nbsp; thanks in advance,<br>-- <br>Lucas Vieites<br>
