In the design, I need to compare the difference of the phase parameter S11 for parameter &#8216;x&#8217; under two different values (for example: &#8216;S11(x=0)-S11(x=1)&#8217; as the optimization goal). So I tried to set up two air boxes and corresponding periodic boundaries, in each box, the modal is same except value of&nbsp; &#8216;x&#8217;. But an error message is returned at runtime: The problem setup may not contain more than two floquet port.&nbsp;&lt;\/p&gt;&lt;p&gt;I wonder if there is limitation about the floquet port. And I want to know how to set optimization goal like: &#8216;S11(x=0)-S11(x=1)&#8217;?&lt;\/p&gt;&lt;p&gt;Thank you very much!&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-395711","topic","type-topic","status-publish","hentry","topic-tag-optimization"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["395711"],"_bbp_subscription":["487125","28551"],"_bbp_author_ip":["138.25.4.60"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["487125","28551"],"_btv_view_count":["179"],"_bbp_topic_status":["unanswered"],"_bbp_last_reply_id":["396078"],"_bbp_last_active_id":["396078"],"_bbp_last_active_time":["2024-12-03 13:29:23"]},"test":"shan-huang-1student-uts-edu-au"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/395711","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\/395711\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=395711"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
