To do this, I need to have wall temperature and bulk temperature. For calculating the bulk temperature, I create several isosurface parallel to the inlet until the outlet. For wall temperature, I have no idea what is the correct way to extract the result. I have tried to create a line at the middle of the wall (between solid and fluid), but I notice there is variation of temperature along the x direction. Z direction is the length, Y direction is the height and X- direction is the width. I need to extract the wall temperature at each position (z = 0mm, z = 1mm, z= 2mm, until z=10mm) to enable me to calculate the local Nusselt number. Any recommendation to use which postprocessing techniques?<\/p>\n","protected":false},"template":"","class_list":["post-168759","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["2106"],"_bbp_likes_count":["0"],"_bbp_subscription":["250375"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["168759"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","176208"],"_bbp_voice_count":["2"],"_bbp_reply_count":["11"],"_bbp_last_reply_id":["212615"],"_bbp_last_active_id":["212615"],"_bbp_last_active_time":["2022-05-06 15:55:43"]},"test":"yew511"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/168759","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\/168759\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=168759"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
