I am trying to simulate flow through it in steady state initially and then later in&nbsp;<\/div>\n<div>unsteady conditions.<\/div>\n<div>With the density based solver I was able to get a decent steady state solution altho the residuals weren&#8217;t perfect. When I started to run the transient solution , my results start diverging near the wall, which I think is caused by high accept ratio cells near the wall\/inflation layers. Without the inflation layers, it is working.<\/div>\n<div>&nbsp;<\/div>\n<div>However, when I use the pressure based solver&nbsp; I am able to get really good results with inflation layers as well. I want to recreate the results using density based solver as Mach number in my flow exceeds 3.<\/div>\n<div>Please let me know how to fix this issue.<\/div>\n<div>I will attach pictures<\/p>\n<p><\/div>\n","protected":false},"template":"","class_list":["post-314614","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["288974"],"_bbp_author_ip":["104.102.248.196"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["444"],"_edit_lock":["1698982757:223521"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["314614"],"_bbp_forum_id":["27792"],"_bbp_engagement":["288974"],"_bbp_voice_count":["1"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["315239"],"_bbp_last_active_id":["315239"],"_bbp_last_active_time":["2023-11-07 12:28:43"]},"test":"ae22b001smail-iitm-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/314614","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\/314614\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=314614"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
