Hello all,<\/p>\n

I am using the field calculator of Ansys HFSS 2023 to compute the power passing through a surface by implementing this equation:<\/p>\n

<\/a><\/p>\n

where W = power [W] , P = Poynting vector [W\/m^2] , integration is made on the surface “S”.<\/p>\n

Here is my issue:
<\/strong>While applying this equation on surfaces at increasing distances from the source in a lossy medium, I see the power decreasing as an exponential (which is the expected behaviour) until a certain distance where it seems to saturate at a value of 1e-5 [W]. I think this is due to numerical accuracy which is too low.<\/p>\n

I therefore would like to increase the number of digits of the saved fields used in this computation.
Do you know any way to do so? <\/p>\n

Best,
Louis <\/p>\n","protected":false},"template":"","class_list":["post-290862","topic","type-topic","status-closed","hentry","topic-tag-ansys-help","topic-tag-ansys-hfss","topic-tag-ansys-issues-1","topic-tag-digital-elevation-model","topic-tag-field-calculator","topic-tag-fields","topic-tag-fieldscalculator-1","topic-tag-simulationaccuracy-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["96.7.218.215"],"_bbp_subscription":["288336","28551"],"_btv_view_count":["791"],"_bbp_likes_count":["1"],"_edit_lock":["1688039686:222648"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["290862"],"_bbp_forum_id":["27793"],"_bbp_engagement":["28551","288336"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["291339"],"_bbp_last_active_id":["291339"],"_bbp_last_active_time":["2023-07-03 18:00:14"]},"test":"louis-delaituclouvain-be"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/290862","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\/290862\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=290862"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
