Its a 3D geometry of mesh size around 10.7 million polyhedra cell. Solution is stuck at 4 ietration since more than 10 hours and now it shows 12127 hours to complete 5000 iterations. I believe it is not solving rather it is stuck. I checked if the memory is full but RAM and CPU is not 100 % utilized yet. I am using standard k-epsilon and partially premixed combustion model. I even tried stopping and reloading the mesh and rerunning it but the issue still remains same.&lt;\/p&gt;&lt;p&gt;I humbly request for suggestions to rectify this problem.&lt;\/p&gt;&lt;p&gt;Thank you.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-459703","topic","type-topic","status-publish","hentry","topic-tag-cfd-combustion","topic-tag-fluent","topic-tag-fluid","topic-tag-hydrogen-combustion"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["459703"],"_bbp_subscription":["540264"],"_bbp_author_ip":["14.139.128.12"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["459703"],"_bbp_last_active_time":["2026-06-13 05:31:11"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["1"],"_bbp_engagement":["540264"],"_btv_view_count":["10"],"_bbp_topic_status":["unanswered"]},"test":"shezanghamatgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/459703","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\/459703\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=459703"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
