I&#8217;m trying to simulate the solar irradiation from the ambient environment to the indoor environment through a glass window. And I&#8217;m using DO and solar irradiation models for this case. The version of Ansys is 2023R2 student. As the figure shows below, the solar ray comes from the left surface. The boundary condition of that surface is pressure-inlet with a transparent setting. For the BC of all the other surfaces in that fluid region is a pressure outlet with an Opaque setting. The horizontal length of the left region is 5 m, but the 1000w\/m2 irradiation attenuated within 5 meters. Could anyone help me out?<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/09\/20-09-2023-1695182211-mceclip0.png\"><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-307534","topic","type-topic","status-closed","hentry","topic-tag-do-radiation-model","topic-tag-error"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["292613","15180"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["276"],"_bbp_likes_count":["1"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["307534"],"_bbp_forum_id":["27792"],"_bbp_engagement":["15180","292613"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["309726"],"_bbp_last_active_id":["309726"],"_bbp_last_active_time":["2023-10-02 22:35:02"]},"test":"s3786324student-rmit-edu-au"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/307534","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\/307534\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=307534"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
