This analysis group calculates power flow in\/out of a box.<\/p>\n<p>Also, I used the analysis group &quot;Power absorbed (advanced)&quot; to calculate Pabs_total as done in the Photothermal heating example. This analysis group uses the Joule heating formula. <\/p>\n<p>My question\/confusion is, are they both not supposed to give the same Pabs_total? However, I am getting different values of Pasb_total. Both analysis groups have the same dimensions in my simple problem. <\/p>\n<p>for example for a 20nm dia gold sphere in water at 1mW\/um2 power intensity at 530 nm, <\/p>\n<p>the total absorbed power (pabs_total) is:<\/p>\n<p>8e-11 W with the analysis group &quot;Power absorbed (advanced)&quot;<\/p>\n<p>2.5e-7 W with the analysis group &quot;cross-section&quot;<\/p>\n<p>as per literature, the value calculated by the analysis group &quot;cross-section&quot; is more reliable.<\/p>\n<p>Can anyone please comment on this?<\/p>\n","protected":false},"template":"","class_list":["post-167698","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["406"],"_bbp_likes_count":["0"],"_bbp_subscription":["241832"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["167698"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","241832"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["209531"],"_bbp_last_active_id":["209531"],"_bbp_last_active_time":["2022-03-24 22:31:12"]},"test":"ferruccio-pisanelloiit-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/167698","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\/167698\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=167698"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
