I used below expression to measure the max shear strain rate:<\/p>\n<p>maxVal(Fluid 2.Shear Strain Rate)@Default Domain<\/p>\n<p>However the maximum shear strain rate reported are in the region that volume fraction is 10^-15 which I assume is not zero due to the diffusion of volume fraction as I am using coupling method. Is there any way to get the right number in monitor during the simulation or I can just get it in post processing by using iso clip. <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/17-04-2023-1681773838-mceclip0.png\"><\/p>\n","protected":false},"template":"","class_list":["post-279899","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["27065","18096"],"_bbp_author_ip":["23.220.96.180"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["361"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["279899"],"_bbp_forum_id":["27792"],"_bbp_engagement":["18096","27065"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["280299"],"_bbp_last_active_id":["280299"],"_bbp_last_active_time":["2023-04-19 10:27:22"]},"test":"isar-charmchiugent-be"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/279899","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\/279899\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=279899"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
