The pipe here under internal pressure,&nbsp; I fixed the both ends so&nbsp; it will not move in any direction and applied the internal pressure, but after doing the simulation the pipe deformed in the way as showed in the picture above which is not supposed to deform like that ! as you see above the pipe got something like swelling which can be noticed with the lite color<\/span>.. I googled this problem but what I got this deformation occurred due wrong constraint or the model has more degree of DOFs, could you just guide me how to model or what is the suitable constraints required for this model.&nbsp; I&#8217;m using ansys workbench 19.0.<\/p>\n<p><\/p>\n<p>I tried also to decrease the value of the internal pressure and the results (for the pipe deformation ) are same .<\/p>\n<p><\/p>\n<p>&nbsp;Thanks in advance&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-31560","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["3732"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["896"],"_bbp_subscription":["237584"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["31560"],"_bbp_forum_id":["27791"],"_bbp_engagement":["62","200","159883"],"_bbp_voice_count":["3"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["69940"],"_bbp_last_active_id":["69940"],"_bbp_last_active_time":["2018-11-20 17:06:59"]},"test":"ammorey"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31560","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\/31560\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=31560"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
