I am not sure, which I can use for the steady-state and unsteady state. In the user manual, it says to use low diffusion discretization must be used only for subsonic flows.&nbsp; In Ansys 18.1 I have just two options like AUSM and ROE-FDS there is nothing like the &quot;Low Diffusion ROE_FDS&quot; scheme. any suggestion for choosing the solver parameter. ?<\/p>\n<p>l<\/p>\n","protected":false},"template":"","class_list":["post-166322","topic","type-topic","status-closed","hentry","topic-tag-compressible-flow","topic-tag-fluent","topic-tag-subsonic-flow-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["1127"],"_bbp_likes_count":["0"],"_bbp_subscription":["241431"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["166322"],"_bbp_forum_id":["27792"],"_bbp_engagement":["118","166775"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["205189"],"_bbp_last_active_id":["205189"],"_bbp_last_active_time":["2022-02-17 03:04:57"]},"test":"88134c33056105b8e0ece9694a640e55816f65a4"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/166322","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\/166322\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=166322"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
