Although most of the simulations(examples) don&#039;t consider ambient pressure ( 101325 Pa), it is important if there&#039;s pressure different between ambient pressure and container pressure as shown in 1st picture. Let&#039;s assume P1 is nearly vacuumed, and P2 is in ambient pressure , which is 101325 Pa. Then the structure below may be collapsed by air if the structure is weak. The second case is when P1 and P2 are the same, let&#039;s say 101325 Pa, than the object should not collapse. <\/p>\n<p>Therefore, the question is , when I applied pressure to all surfaces with 101325 Pa, my structure deformed severely, this means that this structure cannot survive in ambient?(P.S: the structure is made of steel)<\/p>\n<p>Obviously, it seems that I was wrong, therefore, I&#039;m looking for help here about the effect of ambient pressure to the structure and the boundary condition setting of the picture below.<\/p>\n<p><\/p>\n<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/618\/ORGNJWSC5A9N.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/618\/ORGNJWSC5A9N.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-165448","topic","type-topic","status-closed","hentry","topic-tag-ambient-air-2","topic-tag-static-structural"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["1382"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["165448"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","180472","187703"],"_bbp_voice_count":["3"],"_bbp_reply_count":["10"],"_bbp_last_reply_id":["202483"],"_bbp_last_active_id":["202483"],"_bbp_last_active_time":["2022-01-13 04:11:48"]},"test":"eric_lee"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/165448","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\/165448\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=165448"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
