My inlet boundary is a velocity inlet where my outlet is a pressure outlet. My wall boundary is no slip and has a constant temperature flux.&nbsp; Additionally, the nitrogen is assumed to be an ideal gas and I have the source term of gravity on. I am running off of a pressure based solver and have the energy as well as the K-eplison model on.<\/p>\n<p><\/p>\n<p>My issue is in my post-processing. When I am looking at the velocity streamlines my velocity values are not making a lot of sense. My initial value for velocity is 1 m\/s and in the global range its stating my min is 0m\/s and in the local range its much less than 1 m\/s. Can someone please explain to me the difference between the global and local range values and why this would be happening?<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Thanks!&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/71459ac6-f5ad-493a-b7fe-a96d0103efc4\/1be8ec1f-8bae-4d00-9fac-a96d0166dcf9_global1.jpg?width=690&amp;upscale=false\" alt=\"Global Range Streamlines\"><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/71459ac6-f5ad-493a-b7fe-a96d0103efc4\/72200c84-597b-443b-bd9f-a96d0166f192_local1.jpg?width=690&amp;upscale=false\" alt=\"Local Range Streamlines\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-30691","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["2863"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["3770"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["30691"],"_bbp_forum_id":["27792"],"_bbp_engagement":["13","25","62","22555","157440","159148"],"_bbp_voice_count":["6"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["65632"],"_bbp_last_active_id":["65632"],"_bbp_last_active_time":["2018-10-05 01:19:40"]},"test":"rcamp"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/30691","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\/30691\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=30691"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
