(edit&#8230;.I know lumopt is a good tool for this, and it specifically has an example that requires 2 FDTDs (the robust coupler superoptimization)&#8230;but I find that lumopt is more restrictive in how the FOM can be defined.&nbsp; So a solution not using lumopt would be beneficial.)<\/p>\n","protected":false},"template":"","class_list":["post-341609","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["335704","185544"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["205"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1703776022:282184"],"_bbp_status":["publish"],"_bbp_topic_id":["341609"],"_bbp_forum_id":["27833"],"_bbp_engagement":["185544","335704"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["345645"],"_bbp_last_active_id":["345645"],"_bbp_last_active_time":["2024-01-19 21:06:00"]},"test":"brianxscapephotonics-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/341609","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/341609\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=341609"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
