Each model is 50x50x29 mm with cells of roughly 9x10x10 mm and wall size 0,8 mm. I exported them as stl-file to use them in Ansys. After importing the model in Spaceclaim, I did the automatic Facet-Repair and Facet Check. It showed no errors and only the hint that there is one joined knot. I turned the model into a solid body (Volumenk&ouml;rper) and chose the &quot;merge surfaces option&quot;. I got a large .scdoc file, which I imported to Workbench. Now I am having trouble meshing it for future analysis. <\/p>\n<p>The automatic mesh does not work. <\/p>\n<p>The method &quot;Tetraeder&quot; with algorithmus &quot;fl&auml;chenunabh&auml;ngig&quot; and max size of elements (0.005m), min element size (0.002m) and angle of 13.5 degrees gives me errors of negative jakobi-determinante.<\/p>\n<p>Are there parameters, that you would not change and others, that you would recommend adjusting?<\/p>\n<p>I appreciate your help.<\/p>\n<p>BR<\/p>\n<p>Elmano<\/p>\n","protected":false},"template":"","class_list":["post-166808","topic","type-topic","status-closed","hentry","topic-tag-mesh-generation","topic-tag-TPMS-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["3455"],"_bbp_likes_count":["0"],"_bbp_subscription":["249950"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["166808"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","249950","253060"],"_bbp_voice_count":["3"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["206872"],"_bbp_last_active_id":["206872"],"_bbp_last_active_time":["2022-04-19 10:19:04"]},"test":"bt712759myubt-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/166808","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\/166808\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=166808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
