In the regarding documentations it is said, that this boundary condition is allowed for solids in 3D, but only topologies like faces, edges and vertices. Now my question: If I want to model a process pressure in a pipeline, e.g., and then add any load to investigate on the transient answer of the system including sound pressure, how would I define the process pressure? Would I select the &#8220;inlet&#8221; surface of the process medium for instance and would that mean that the pressure in the whole acoustic region is the same (as I want it initially)?<\/p>\n<p>I tried one-way coupling with Fluent to import the pressure as load to my Coupled Field Transient analysis, but it seems easier to use Mechanicals own features. Also, through the coupling, I only can import surface pressures that affect structural regions (so no chance of applying the pressure on the acoustic region), therefore the inbuilt feature seems more adequate.<\/p>\n<p>Looking forward to your answers and suggestions!<\/p>\n","protected":false},"template":"","class_list":["post-241837","topic","type-topic","status-closed","hentry","topic-tag-acoustics","topic-tag-mechanical","topic-tag-pressureload-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["25225","58821"],"_bbp_author_ip":["23.48.209.37"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1139"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["241837"],"_bbp_forum_id":["27791"],"_bbp_engagement":["25225","58821"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["241936"],"_bbp_last_active_id":["241936"],"_bbp_last_active_time":["2022-11-24 13:15:46"]},"test":"a-l-obermannweb-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/241837","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\/241837\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=241837"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
