I am using the combusting particle and the multiple surface reactions model and I can specify the all other relevant properties such as the combustible mass fraction (which I set to 100%) and the reaction heat fraction absorbed by the solid (30%).nHow can I include the heat of reaction when it is not shown in my dialog box?n<\/p>\n","protected":false},"template":"","class_list":["post-48155","topic","type-topic","status-closed","hentry","topic-tag-cfd-combustion","topic-tag-combustion","topic-tag-dpm","topic-tag-particle-surface-reaction","topic-tag-udf-fluent"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["20371"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["??\tj"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1299"],"_bbp_subscription":["248497"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["48155"],"_bbp_forum_id":["27792"],"_bbp_engagement":["170619","174280"],"_bbp_voice_count":["2"],"_bbp_reply_count":["10"],"_bbp_last_reply_id":["127400"],"_bbp_last_active_id":["127400"],"_bbp_last_active_time":["2020-09-17 14:33:08"]},"test":"jeroen"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/48155","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\/48155\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=48155"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
