Note: Even when the SOFC module is used without the diffusion coefficient, kinetic theory and unique it is also possible to use a UDF. <\/p>\n<p>Attachments:<br \/>\n1. <a href=https:\/\/ansys13.ansys.com\/KnowledgeArticles\/Phase-3\/2043239\/2043239.pdf>2043239.pdf<\/a><\/p>\n","protected":false},"template":"","class_list":["post-178988","topic","type-topic","status-publish","hentry","topic-tag-14-5","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-modeling-setup-advice","topic-tag-species-reactions"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"siebel_km_number":["2043239"],"_bbp_last_active_time":["8\/25\/2023 20:20"],"_bbp_forum_id":["27784"],"_bbp_author_ip":["23.56.168.180"],"application_name":["FLUENT"],"family":["Fluid Dynamics"],"km_published_date":["2016-09-15T00:00:00.000Z"],"product_version":["14"],"_btv_view_count":["717"],"_bbp_likes_count":["0"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/178988","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\/178988\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=178988"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
