I am doing a natural convection flow! There are only Wall B.C and Symmetry B.C for my domain. I am looking at many discussions in this forum, also in the fluent manual, I am still not sure whether I choose Pressure Based Solver or Density Based Solver for my domain. Density Based Solver is suitable for the fast speed of the flow. Pressure Based Solver is suitable for low speed of the flow and the results are derived from the pressure equation, but in my simulation, it is the natural convection flow, so the important variables are only density, gravity and thermal expansion coefficient. There is no initial pressure at all, thus should I use Density Based Solver? Thank You in advance!<\/p>\n","protected":false},"template":"","class_list":["post-159966","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["13303"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["941"],"_bbp_subscription":["255146"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159966"],"_bbp_forum_id":["27792"],"_bbp_engagement":["22555","181026"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["184001"],"_bbp_last_active_id":["184001"],"_bbp_last_active_time":["2021-06-30 07:21:06"]},"test":"seanghai"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159966","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\/159966\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159966"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
