But then it will give the following error as shown in the screenshot. <\/p>\n<p>However, if I implement this for loop (basically just switchtolayou; run;) directly in a .lsf file, it seems no error would pop up and Lumerical would finish all five simulations. Due to the use of optimization, I have to interface with matlab. <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/058\/QQQWNSNOA4KL.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/058\/QQQWNSNOA4KL.png\" alt=\"Screen Shot 2021-07-26 at 1.02.46 PM.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-160711","topic","type-topic","status-closed","hentry","topic-tag-fdtd","topic-tag-matlab","topic-tag-optimization"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["481"],"_bbp_likes_count":["0"],"_bbp_subscription":["238865"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160711"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","199697"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["186771"],"_bbp_last_active_id":["186771"],"_bbp_last_active_time":["2021-07-27 16:55:19"]},"test":"xiaochenxincmailc-carleton-ca"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160711","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\/160711\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160711"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
