I have simulated supersonic flows (density-based, k-epsilon, ideal-gas, pressure-farfields as boundary conditions, etc.) Now, I need to simulate the reaction, and the only model allowed when using density-based is species transport. I turn on volumetric reactions, eddy-dissipation, and hydrogen-air species. I keep getting these errors with these settings, and I do not know how to fix them. Any help will be greatly appreciated. First picture is the cross section of engine and second picture is the errors.<img decoding=\"async\" src=\"https:\/\/preview.redd.it\/fluent-supersonic-engine-v0-9r7n5e9xxiuc1.png?width=1867&amp;format=png&amp;auto=webp&amp;s=ecac472ac817cd57e7a0e462fc1fe69e2e306740\" alt=\"r\/CFD - Fluent Supersonic Engine\"><img decoding=\"async\" src=\"https:\/\/preview.redd.it\/fluent-supersonic-engine-v0-feg9sft2yiuc1.png?width=1359&amp;format=png&amp;auto=webp&amp;s=9386a9d1cdce0d2dd33e42bf8e3bbc898a93f253\" alt=\"r\/CFD - Fluent Supersonic Engine\"><\/p>\n","protected":false},"template":"","class_list":["post-362349","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["343716","199"],"_bbp_author_ip":["23.52.43.88"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["172"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["362349"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","343716"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["362444"],"_bbp_last_active_id":["362444"],"_bbp_last_active_time":["2024-04-16 10:35:38"]},"test":"ndonetoiastate-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/362349","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\/362349\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=362349"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
