My current method is to run one of the mode, save it as D-deck card, run the second mode and use Overlap analysis tab for power overlap, this can be automated by script using Optimizeposition and Overlap script commands.&lt;br&gt;However, I would like to use the Sweep and\/or Optimization Parameters tools as they can bring several advantages in terms of efficiency and simulation in parallel. My challenge is to build the figure of merit of the coupling as it is obtained by calculation.&lt;\/p&gt;&lt;p&gt;I tried to employ the script into an Analysis Group object to output a single figure of merit to useas result into the Sweep and\/or Optimization Parameters tools. The problem I encontered is that Analysis Group script doesn&#8217;t have access to anything in the D-card and in the Workspace so basically there is no way to employ any result from a previous FDE simulation.&nbsp;&lt;\/p&gt;&lt;p&gt;Could you please suggest a way to circumvent this issue and be able to optimise the FDE waveguide coupling using Sweep and Optimization Parameters tools?&lt;\/p&gt;&lt;p&gt;Thanks in advance for your help!&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Regards&lt;\/p&gt;&lt;p&gt;Eugenio&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-438252","topic","type-topic","status-publish","hentry","topic-tag-FDE-1","topic-tag-optimisation-2","topic-tag-overlap","topic-tag-parametersweep-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27833"],"_bbp_topic_id":["438252"],"_bbp_subscription":["242609","294329"],"_bbp_author_ip":["130.209.178.213"],"_bbp_last_reply_id":["438372"],"_bbp_last_active_id":["438372"],"_bbp_last_active_time":["2025-08-01 13:45:12"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["242609","294329"],"_btv_view_count":["379"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1753974908:473055"],"_bbp_notification_enabled":["473055"]},"test":"eugenio-digaetanoglasgow-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/438252","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\/438252\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=438252"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
