When I monitor my residuals and temperature vs iterations, I&#039;m getting very high fluctuations in both my residuals and temperature and the images are uploaded. I have tried mesh refinement and also with different under relaxation factors. I&#039;m using boussinesq approximation with operating temperature of melting temperature of liquid part. I have also tried piecewise linear and also polynomial variation of density in addition to this but couldn&#039;t find solution. The geometry is like cylinders inserted in the mould of melting material with 5 walls except on the top and the cylinders are given heat flux. Anyone please help me out on this. <\/p>\n<p>Thanks in advance <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/B5PE6BK31DDU\/residuals-png.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/B5PE6BK31DDU\/residuals-png.png\" alt=\"residuals.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-51652","topic","type-topic","status-closed","hentry","topic-tag-ansys-fluent","topic-tag-convergence","topic-tag-pcm"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23925"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["??>]"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["890"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["51652"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","185483"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["140281"],"_bbp_last_active_id":["140281"],"_bbp_last_active_time":["2021-01-28 10:22:18"]},"test":"sandeep_dattu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/51652","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\/51652\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=51652"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
