I am using:<\/p>\n<p>1- inclined injection not perpendicular injection (angle theta =16.7 instead of 0)<\/p>\n<p>2- 90 polarized incident wave instead of 0 polarized wave, please check photo 1 to see my settings<\/p>\n<p>I have a question regarding the boundary conditions I should use. I believe that I should use symmetric for x-min &amp; x-max and anti-symmetric for y-min &amp; y-max, is it right please? Or should I use periodic boundary condition for both x and y directions? Please let me know the correct one and why, thanks. Also, do I need to change any other settings away from the boundary condition to consider the inclined injection and 90 polarized wave? <\/p>\n<p><\/p>\n<p><\/p>\n<\/p>\n<div data-embedjson=\"{&quot;url&quot;:&quot;\/forum\/wp-content\/uploads\/forum-uploads\/465\/4HBYN58VPGP0.png&quot;,&quot;name&quot;:&quot;1.PNG&quot;,&quot;type&quot;:&quot;image\/png&quot;,&quot;size&quot;:59521,&quot;width&quot;:null,&quot;height&quot;:null,&quot;embedType&quot;:&quot;file&quot;}\">\n<a href=\"\/forum\/wp-content\/uploads\/forum-uploads\/465\/4HBYN58VPGP0.png\" download aria-label=\"1.PNG\"><br \/>\n1.PNG<br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-161752","topic","type-topic","status-closed","hentry","topic-tag-LumericalFDTD-1"],"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":["661"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["161752"],"_bbp_forum_id":["27833"],"_bbp_engagement":["707","2192","30281"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["190383"],"_bbp_last_active_id":["190383"],"_bbp_last_active_time":["2021-09-08 13:59:41"]},"test":"amora"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/161752","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\/161752\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=161752"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
