If you  remove the second stream from the PDF,  you will be able to activate the inert model to add a transport equation for the inert.  In this situation, the PDF gets accessed with conditioned variables that account for the presence of the inert.  It is a valid approach, since the inert is just a diluent, and saves you a transport equation.<\/p>\n","protected":false},"template":"","class_list":["post-167011","topic","type-topic","status-publish","hentry","topic-tag-4391","topic-tag-bcs-interfaces","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-materials","topic-tag-species-reactions"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["5\/4\/2023 20:20"],"_bbp_forum_id":["27784"],"_bbp_author_ip":["209.182.204.162"],"_btv_view_count":["443"],"siebel_km_number":["2054682"],"product_version":["19"],"km_published_date":["2018-05-30T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["FLUENT"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/167011","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/167011\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=167011"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
