In my project I am trying to identify the operational limits for the amount of clamping force that can be applied to the gaskets without causing permanent deformation. I have carried out experimental work and I am now aiming to validate this through FEA. I have modelled the gasket as 2D axisymmetric with the two rectangles above and below the gasket representing the flanges. One flange&nbsp;will have a fixed support along the bottom edge and the other flange will have a force of 18730N applied to the top edge (This force is the minimum force calculated to form a reliable seal).<\/p>\n<p><\/p>\n<p>I have managed to get this far without too much problems but when I try to add the contact regions between the flanges and the gaskets and then solve for the total deformation of the gasket the message appears that I have&nbsp;&#8216;An internal solution magnitude has been reached.&#8217;<\/p>\n<p><\/p>\n<p>Does anyone know how to change the solution magnitudes or have any other recommendations on how to simulate?<\/p>\n<p><\/p>\n<p>Cheers<\/p>\n<p><\/p>\n<p>Calum<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-34341","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["6513"],"_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"],"_btv_view_count":["466"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["34341"],"_bbp_forum_id":["27791"],"_bbp_engagement":["897","160648","163967"],"_bbp_voice_count":["3"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["81738"],"_bbp_last_active_id":["81738"],"_bbp_last_active_time":["2019-03-30 06:28:13"]},"test":"calumsangster"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/34341","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\/34341\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=34341"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
