However, when the material is changed to <strong>n2<\/strong>, the FDTD mesh grid is recalculated, and the number of grids changes. Is there a way to fix the number of mesh grids so that it remains constant even when the material is changed?&lt;\/p&gt;&lt;\/div&gt;&lt;\/div&gt;&lt;\/div&gt;&lt;\/div&gt;&lt;\/div&gt;&lt;\/div&gt;<\/p>\n","protected":false},"template":"","class_list":["post-396741","topic","type-topic","status-publish","hentry","topic-tag-lumerical","topic-tag-LumericalFDTD-1","topic-tag-mesh","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27833"],"_bbp_topic_id":["396741"],"_bbp_subscription":["483297","473055"],"_bbp_author_ip":["143.248.37.29"],"_bbp_last_reply_id":["396845"],"_bbp_last_active_id":["396845"],"_bbp_last_active_time":["2024-12-09 19:32:44"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["483297","473055"],"_btv_view_count":["122"],"_bbp_topic_status":["unanswered"],"_bbp_notification_enabled":["473055"]},"test":"dho0106kaist-ac-kr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396741","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\/396741\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=396741"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
