I have been selecting the first mode that appears after calculating the modes and checking off the &#8216;Track selected Mode&#8217; button. However, I am not sure how it is obtaining the results because when I go and manually enter the frequencies it is sweeping through, I get my fundamental mode to have a different effective refractive index than the one shown in the sweep. What could be the reason for that? Would I have to write a script to pick out the fundamental TE mode every iteration of the sweep? If so, how can I do that? I would appreciate any help, thank you.<\/p>\n","protected":false},"template":"","class_list":["post-299433","topic","type-topic","status-closed","hentry","topic-tag-ansys-discovery"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["20505"],"_btv_view_count":["96"],"_bbp_likes_count":["0"],"_bbpmt_movedon":["2023-08-17 12:10:23"],"_bbpmt_movedfrom":["296275"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["299433"],"_bbp_forum_id":["27789"],"_bbp_engagement":["2328","20505"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["300199"],"_bbp_last_active_id":["300199"],"_bbp_last_active_time":["2023-03-23 03:35:47"]},"test":"asharma007citymail-cuny-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/299433","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\/299433\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=299433"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
