I am using the FDE solver and I am trying to understand how the simulation region and the mesh size effects the loss on modes.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;When I perform the convergence tests, I can still see that the loss keeps increasing with increasing mesh points and increasing simulation region even though the effective index stays pretty much the same. How do I decide the correct parameters in this case? I can just pick a combination of simulation region size and numbe rof mesh points where they seem to obey the convergence test but the loss values of the fundamental TE mode are wildly different.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Putting in simpler words, what is the relation between loss (dB\/cm) vs number of mesh points and loss (dB\/cm) vs simulation region size?&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Let me know if I was able to make the problem clearer.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-295179","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/295179","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/295179\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=295179"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
