Dear Experts,
I am performing a coupled Analysis, Steady state thermal followed by Static structural analysis using ANSYS workbench – 2023 R2 version. The FE model is having combination of a column and vessels connected together through nozzles and intent of analysis is to obtain the reaction loads due to thermal growth along with other static structural load like pressure, thrust and self-weight of the equipment at the nozzle \/ structural connections.<\/p>\n
Boundary condition:
Column (center equipment) skirt is constrained at all x, y and z direction.
Vessels at both sides are mounted on the column by structural supports and connected through nozzles.
we used remote point and followed by remote displacement to fixed 6 DOF at where reaction is requested from FE model.<\/p>\n
We used Solid elements, Quad mesh using shared topology with Symmetry model in ANSYS workbench and successfully import the temperature on the model. While running the static structural analysis, we get the following error and unable to complete the analysis further. Solution is interrupted.<\/p>\n
My understanding is since i used shared topology method , all mesh are connected together with out any contact (gap) issues, hence there should not be any chance for rigid body motion in the model. <\/p>\n
Error message is as below: Requesting your guidance to fix this error, as early as possible.<\/p>\n Thank you.<\/p>\n Regards<\/p>\n AE<\/p>\n <\/p>\n <\/p><\/p>\n","protected":false},"template":"","class_list":["post-317298","topic","type-topic","status-closed","hentry","topic-tag-ansysworkbench-ansys-staticstructural","topic-tag-mechanicalworkbench-1","topic-tag-3-d-model","topic-tag-vessel","topic-tag-workbench"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["42166","240"],"_bbp_author_ip":["104.102.248.196"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2852"],"_edit_lock":["1700106381:236985"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["317298"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","42166"],"_bbp_voice_count":["2"],"_bbp_reply_count":["10"],"_bbp_last_reply_id":["317902"],"_bbp_last_active_id":["317902"],"_bbp_last_active_time":["2023-11-16 02:54:16"]},"test":"govindankrishna2hotmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/317298","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\/317298\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=317298"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
