It&#8217;s a Multiphase simulation using VOF. One inlet and outlet. But I found that Static Pressure is quite different from steady flow when I read steady result into transient case. Image on the left is the Static Pressure in steady flow and the right is the one after enabling VOF model and reading steady data.&nbsp;<\/p>\n<p>Though it&#8217;s a little strange but the increased pressure seemed to be reasonable in transient case due to the height of about 6.5 meters.&nbsp;<\/p>\n<p>How can we explain for the situation?<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/23-07-2024-1721703912-mceclip2.png\"><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/23-07-2024-1721703955-mceclip3.png\"><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-373152","topic","type-topic","status-closed","hentry","topic-tag-different-solution-1","topic-tag-fluent","topic-tag-ImplicitVOF-1","topic-tag-transient"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["51510","199"],"_bbp_author_ip":["2001:250:3002:3270:7f84:d980:f12:d1e5"]," _bbp_last_reply_id":["0"],"_btv_view_count":["206"]," _bbp_likes_count":["0"],"_bbp_likes_count":["1"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["373152"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","51510"],"_bbp_voice_count":["2"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["373415"],"_bbp_last_active_id":["373415"],"_bbp_last_active_time":["2024-07-24 13:12:00"]},"test":"bfdef4e41fe840e99014e0c0ef18055b3cd7380f"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/373152","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\/373152\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=373152"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
