This is not recommended&#8217; Please consider changing your mesh settings to use a different element type in these regions&#8217; nI am trying to model different porosities of a scaffold for 3D bioprinting. What is really confusing me is that it works for 78% porosity which has 1,767,476 elements and the one I am trying to model now has 1,722,296 elements and it is failing even though it has less elements that the one that is working. I used exact same mesh settings\/BC on both. nThanks n<\/p>\n","protected":false},"template":"","class_list":["post-53850","topic","type-topic","status-closed","hentry","topic-tag-error","topic-tag-failed","topic-tag-solver"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["26173"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["3%?\u001e"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["888"],"_bbp_subscription":["233223"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["53850"],"_bbp_forum_id":["27789"],"_bbp_engagement":["185297","187303"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["148249"],"_bbp_last_active_id":["148249"],"_bbp_last_active_time":["2021-03-26 07:52:00"]},"test":"sophiemcg"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53850","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\/53850\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=53850"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
