Decreasing mesh size leads to increased stress focused on just one node if looking at nodal stresses (average). Now the question is, if it is good practice to evaluate stresses by looking at elemental stress instead of nodal results?&nbsp;<\/p>\n<p>As I would like to automate the post-processing, I would like to extract the max\/min values but in case of a stress concentration\/singularity, I am forced to check the model manually. Using elemental results would probably help as it kind of average out the peaks. But is still a feasible approach?<\/p>\n<p>Generally, we are looking at max.\/min. principal stress due to the material behaviour and not equivalents if that is of any importance.<\/p>\n<p>Mesh size (0.0075 mm)<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676465917-mceclip3.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676465917-mceclip3.png\"><\/a><\/p>\n<p>Nodal results (averaged)<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676465761-mceclip1.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676465761-mceclip1.png\"><\/a><\/p>\n<p>Nodal results (unaveraged)<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676465836-mceclip2.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676465836-mceclip2.png\"><\/a><\/p>\n<p>Elemental results<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676466136-mceclip4.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/02\/15-02-2023-1676466136-mceclip4.png\"><\/a><\/p>\n","protected":false},"template":"","class_list":["post-250005","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["96.7.74.191"],"_bbp_subscription":["34473","58821","267323"],"_btv_view_count":["1202"],"_edit_lock":["1676615750:206199"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["250005"],"_bbp_forum_id":["27791"],"_bbp_engagement":["34473","58821","267323"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["250549"],"_bbp_last_active_id":["250549"],"_bbp_last_active_time":["2023-02-20 07:25:21"]},"test":"dario-denzlerceleroton-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/250005","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\/250005\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=250005"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
