Hello everybody,<\/p>\n

I am trying to simulate a supersonic flow throguh an air intake.<\/p>\n

The final aim of the project is to reproduce the results reported in a reference paper, but my residuals are not converging.<\/p>\n

\"\"<\/a><\/p>\n

The mesh I have used for the simulation is the following:<\/p>\n

\"\"<\/a><\/p>\n

The density-based (coupled) implicit double precision Fluent solver has been set.<\/p>\n

For the inlet I set a farfield bc with a Mach number equals to 2.41.<\/p>\n

For the outlet I set a pressure-outlet bc with zero pressure.<\/p>\n

The CFL was fixed at 0.5.<\/p>\n

All of these conditions come from the reference paper.<\/p>\n

I have also tried to switch to a pressure-based solver, but the solution get even worse.<\/p>\n

What might be the issue?<\/p>\n","protected":false},"template":"","class_list":["post-307063","topic","type-topic","status-closed","hentry","topic-tag-CFDSolver-1","topic-tag-residuals","topic-tag-supersonic","topic-tag-supersonic-flow-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["181274","8124","199"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["443"],"_edit_lock":["1694850973:66287"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["307063"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","8124","181274"],"_bbp_voice_count":["3"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["310683"],"_bbp_last_active_id":["310683"],"_bbp_last_active_time":["2023-10-09 16:17:21"]},"test":"felice_lucivero"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/307063","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\/307063\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=307063"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
