To be specific for my questions:nIf one-to-one mapping is not needed between the meshed model in Fluent and Mechanical, is there any other requirement I need to be careful?nDo the geometry (the geometry from SpaceClaim) need to be exactly same?nThe walls\/wall shadow in Fluent, which are autogenerated between regions, can the results at the wall location be transferred into Mechanical? This wall is a steel structural plate separating two air regions.nThe wall\/wall shadow pair is between two fluid regions (both are air) in FluentnThe wall is suppose to be a thin steel plate, which in fluent is just a wall BC with a thickness assigned and layer conduction activated.nIn mechanical, if this wall is a shell-meshed area (not solid). Is this meshed area mappable from fluent wall results? (Fluent has this wall as a wall between solids, ie an area between fluids, not a dedicated area for wall simulation)nAdditional question : I am trying to model steel bridge box girder (thin steel plate wrapping as a box), the air outside of the girder, and the air inside of the girder in Fluent. nShould I use area and shell element for the steel? nOr should I use really thin solid element for the steel in Fluent? (steel box is about 30m long, 2m high, 3m wide, and 10mm thickness). nI am having a hard time determining which way is the best &#8211; (a) thin plate sounds like a good fit for area and shell, but Fluent is giving me hard time when using water-tight geometry workflow for meshing.nnThanks very much!nBrandonn<\/p>\n","protected":false},"template":"","class_list":["post-52132","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["24416"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["A???"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["2607"],"_bbp_subscription":["254904"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["52132"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","20093","180791"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["142601"],"_bbp_last_active_id":["142601"],"_bbp_last_active_time":["2021-02-16 17:37:22"]},"test":"jiezougt"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/52132","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\/52132\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=52132"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
