Hi,<\/p>\n

I am beginner in Ansys s at the moment struggling with things that can reults easy for other but I have two issues:<\/p>\n

1- After running a 24 timesteps (1 day) solar load calculation (only activated solar ray tracing\/fear weather condition) of a stand-alone buiding in ansys (image “1”),<\/p>\n

\"\"<\/a><\/p>\n

 I want to get for each time step of my simulation (i.e. for the facade south of the builfing) (unique value in each timestep) : the sun vector postion, ambient temperature (or ambeint temperature inside my domain), and the contribution of beam, diffuse and ground reflected radiation in “Solar heat flux” (imafe “3”) as outputs of my simulation to understand how solar ray tracing works.<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

How can I do it? what are exactly the steps I need to follow?<\/p>\n

2- When I want to add a model such as SFS and DO, run the simulation and compare the heat flux values for each building facade and contour heat flux distribution across the façade (image 2)<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

i get the same values of heat flux and countour figure for each timestep (not all time steps exactly the same value unless at 1 pm for case 1, 2 and 3 for example: 134 Wm-2, at 4 pm for case 1, 2 and 3: 88 Wm-2 and so on) for all three cases with no difference<\/p>\n

case 1- only solar ray tracing<\/p>\n

2- solar ray tracing + DO<\/p>\n

3- solar ray tracing + S2S<\/p>\n

i expected to see for example for the case 1, something like image “2” but for the case 3 something like figure “4” see below with also different heat flux value in each time step comparing each case.<\/p>\n

\"\"<\/a><\/p>\n

when I apply DO or S2S only with no solay ray tracing in both, I get these images below where heat flux values are close to 0<\/p>\n

\"\"<\/p>\n

 <\/p>\n

\"\"<\/p>\n

I hope to explain my issues properly and I am sure this post will help many beginners that needs to understand solar load calculation how works.<\/p>\n

Regards and thanks in advance<\/p>\n","protected":false},"template":"","class_list":["post-366083","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["346784","62293"],"_bbp_author_ip":["23.192.127.11"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["300"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1715179461:306657"],"_bbp_topic_id":["366083"],"_bbp_forum_id":["27792"],"_bbp_engagement":["62293","346784"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["366759"],"_bbp_last_active_id":["366759"],"_bbp_last_active_time":["2024-05-14 11:39:04"]},"test":"albertoalmoldalive-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/366083","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":3,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/366083\/revisions"}],"predecessor-version":[{"id":366125,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/366083\/revisions\/366125"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=366083"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
