Hello all,<\/p>\n

I’m running a transient simulation in Fluent and I want to define a non-constant fluid inlet temperature.<\/p>\n

My inlet temperature depends on the temperature of a cell zone and I know what the inlet temperature should be at different temperatures of that cell zone. I need Fluent to interpolate the inlet temperature between the ranges and not change abruptly (which I could even do manually).<\/p>\n

For example,<\/p>\n

At 650°C of cell zone, inlet temperature = 100°C,
At 600°C of cell zone, inlet temperature = 80°C,
At 500!C of cell zone, inlet temperature = 55°C,<\/p>\n

…and so on.<\/p>\n

Thank you! <\/p>\n","protected":false},"template":"","class_list":["post-247128","topic","type-topic","status-closed","hentry","topic-tag-fluent-cfd-ansys-1","topic-tag-expression","topic-tag-inlet-boundary-condition-1","topic-tag-temperature-dependant","topic-tag-udf"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["270815","15180"],"_bbp_author_ip":["23.192.164.18"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1813"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["247128"],"_bbp_forum_id":["27792"],"_bbp_engagement":["15180","270815"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["247197"],"_bbp_last_active_id":["247197"],"_bbp_last_active_time":["2023-01-23 04:40:50"]},"test":"y-sajikumar-paitu-bs-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/247128","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\/247128\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=247128"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
