I used an additive manufacturing software (uses Open Cascade kernel) to generate the geometry, imported in .STEP format and performed all the repair functions in SpaceClaim before using ANSYS Meshing. I also have access to Autodesk Inventor, but I am not sure if I can perform any repairs therein. <\/p>\n<p>I have attached images of the error and my geometry below. I heartily appreciate anyone&#039;s help in performing the repairs or finding a way out.<\/p>\n<p>Thank you in advance.<\/p>\n<\/p>\n<p>Error &#8211; &quot;Overflow or underflow in the arithmetic operation&quot;<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/904\/QOUS5D5J1B0W.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/904\/QOUS5D5J1B0W.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-160730","topic","type-topic","status-closed","hentry","topic-tag-meshing","topic-tag-repair"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["1045"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160730"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","199","183715"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["186814"],"_bbp_last_active_id":["186814"],"_bbp_last_active_time":["2021-08-03 13:33:55"]},"test":"rajas"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160730","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\/160730\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160730"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
