Hello,
I’m a beginner and I’m working on a university project where I need to perform a thermal analysis on a simplified satellite model. When I set up the radiative heat transfer, the software asks me to set the emissivity coefficient and the ambient temperature. I’ve conducted several simulations with different ambient temperature values and noticed that it significantly affects the temperature of the satellite. Since it’s LEO, I kept it within a range of -100 to +60 (°C), instead of setting it to 0 K. Do you think this approach is correct, or is there a way to convey to ANSYS that I’m in a vacuum and thus don’t want to consider the ambient temperature?<\/p>\n

Thank you for your help.<\/p>\n","protected":false},"template":"","class_list":["post-350760","topic","type-topic","status-closed","hentry","topic-tag-ansys-thermal-1","topic-tag-steady-state-thermal"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["339011","240","340040"],"_bbp_author_ip":["23.206.193.59"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["855"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1707727166:287774"],"_bbp_topic_id":["350760"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","339011","340040"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["353980"],"_bbp_last_active_id":["353980"],"_bbp_last_active_time":["2024-02-27 08:52:29"]},"test":"il-salernostudenti-unina-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/350760","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\/350760\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=350760"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
