I want to apply fluid pressure at three surfaces: 1) inner surface of the wellbore 2) inner surface of the casing and 3) outer surface of the casing using the following code:<\/p>\n<p>esel,s,TYPE,,VMIN<\/p>\n<p>sfe,all,,pres,1,7.58e6<\/p>\n<p>allsel<\/p>\n<p>&nbsp;<\/p>\n<p>esel,s,TYPE,,VMIN<\/p>\n<p>sfe,all,,pres,1,7.58e6<\/p>\n<p>allsel<\/p>\n<p>&nbsp;<\/p>\n<p>esel,s,TYPE,,VMIN<\/p>\n<p>sfe,all,,pres,1,7.58e6<\/p>\n<p>allsel<\/p>\n<p>&nbsp;<\/p>\n<p>What should be the value of VMIN? Is it the surface ID&#8217;s on which I want to apply the fluid pressure?<\/p>\n<p>N.B.: I tried to extract surface ID from the worksheet but I was unable to do so because it was deactivated even after solving with some random value of VMIN. Can anybody tell me why is it grey even after solution?<\/p>\n<p>Thanks in advance.<\/p>\n","protected":false},"template":"","class_list":["post-339225","topic","type-topic","status-closed","hentry","topic-tag-ansysworkbench-ansys-staticstructural","topic-tag-mechanicalworkbench-1","topic-tag-ansys-mechanical-apdl","topic-tag-mechanical","topic-tag-static-structural","topic-tag-structural"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["23.52.43.81"],"_bbp_subscription":["296047","170445"],"_btv_view_count":["4551"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1702955646:235632"],"_bbp_status":["publish"],"_bbp_topic_id":["339225"],"_bbp_forum_id":["27791"],"_bbp_engagement":["170445","296047"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["341523"],"_bbp_last_active_id":["341523"],"_bbp_last_active_time":["2023-12-21 10:30:27"]},"test":"fan134uregina-ca"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/339225","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\/339225\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=339225"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
