Good Afternoon,<\/p>\n
<\/p>\n
I have been trying to complete a relatively simple project in which i need to find the maximum stresses present on a bracket that is being subjected to a specified load. Unfortunately, generally, with increasing mesh density, the stresses increase exponentially, and this continues onward. I suspect i have an issue with the way the problem is set up in the program. In order to speed up the entire process of convergence, i have utilized adaptive mesh refinement, but even after letting the program run all night, there is no convergence whatsoever even though the program do come to a result with each loop.<\/p>\n
<\/p>\n
Any ideas?<\/p>\n
<\/p>\n
I am also having plenty of issues uploading an image here…<\/p>\n

Long story short, the program is modeled as an L bracket attached to the underside of a desk. A moment and a force is applied at the bottom of the L bracket, whereas the top is held up to the underside by the 2 screws. I have a rough contact connection between the L bracket and the desk, a bonded contact between the screw flange and the bracket, and a bonded contact between the screw and the holes within the “desk”. I am expecting there to be stresses near the screws and maybe a very small deformation where parts of the bracket is lifted off of the desk due to the force pulling downwards (or not). I have increasing stresses occurring at the edge of the holes where the screws are supporting the bracket.<\/p>\n

Hopefully, somebody can help. I’ve been working on this for a couple days now, and i’ve just about ran out of ideas.<\/p>\n","protected":false},"template":"","class_list":["post-39268","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["11447"],"_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"],"_btv_view_count":["10083"],"_bbp_subscription":["245373"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["39268"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","171026"],"_bbp_voice_count":["2"],"_bbp_reply_count":["14"],"_bbp_last_reply_id":["100104"],"_bbp_last_active_id":["100104"],"_bbp_last_active_time":["2019-12-06 04:46:44"]},"test":"ketsui"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/39268","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\/39268\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=39268"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
