It is giving different values as compared to gradient calculated from Paraview from the same fluent data. Also when i calculate the gradient of square of velocity it gives 0 but in should not be zero. I am defining a new variable and using Gradient option to calculate the gradients in CFDPost. Any suggestions why this discrepancy is coming.&lt;\/p&gt;&lt;p&gt;anny help?? thanks&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-431870","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["431870"],"_bbp_subscription":["296506","39507"],"_bbp_author_ip":["129.11.145.115"],"_bbp_last_reply_id":["432069"],"_bbp_last_active_id":["432069"],"_bbp_last_active_time":["2025-05-20 12:27:45"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["296506","39507"],"_btv_view_count":["78"],"_bbp_topic_status":["unanswered"]},"test":"scaboleeds-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/431870","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\/431870\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=431870"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
