I have added a new monitor (cross_section_mode_monitor) and disabled the existing one (Field_profile) accordingly, but when I run the simulation, no results are loading into the new monitor and I cannot visualize the YZ field. Will you please let me know what I am doing wrong here? This forum does not allow me to upload .lms files so I have attached a screenshot of the new YZ monitor settings. Is there a way I can upload my .lms file? I am using Lumerical through a university license. <\/p>\n<p>Also, what is the best approach (EME\/varFDTD\/FDTD?) if I want to simulate the output only of an adiabatic waveguide taper with sub-wavelength features? I am not optimizing the taper length, etc. but only need an accurate mode profile at the narrow tip of the taper. I will then calculate the overlap between the taper mode and a fiber mode. Thank you.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/168\/1NCB7VXAV67B.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/168\/1NCB7VXAV67B.png\" alt=\"Screen Shot 2022-01-27 at 1.39.39 PM.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-165906","topic","type-topic","status-closed","hentry","topic-tag-LumericalEME-1","topic-tag-LumericalMode-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["2670"],"_bbp_likes_count":["0"],"_bbp_subscription":["246685"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["165906"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","246685"],"_bbp_voice_count":["2"],"_bbp_reply_count":["19"],"_bbp_last_reply_id":["203939"],"_bbp_last_active_id":["203939"],"_bbp_last_active_time":["2022-02-09 23:54:07"]},"test":"aberg05mit-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/165906","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\/165906\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=165906"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
