I have tried to create two group of objects by “duplicate along line(Attach To Original Object)”&”Thicken sheet”, but I finally got “unclassified” objects.<\/p>\n

(For example the following “Group B” became “unclassified” after “Thicken sheet”, even if every hexagon is simply proximity\/attach to the others rather than intersecting)<\/p>\n

While trying to find out the problem,  it seems that boolean operations(especially subtract&intersect) cannot be performed correctly in some cases, as shown.<\/p>\n

Group A: selected result of rectangles substract rows of hexagons<\/p>\n

<\/a><\/p>\n

Group B: selected array of hexagons<\/p>\n

<\/a><\/p>\n

result of subtract(A-B),which is obviously incorrect<\/p>\n

<\/a><\/p>\n

Rectangle C: A rectangle larger than Group B<\/p>\n

<\/a><\/p>\n

result of intersect(B&C),which is obviously incorrect too.<\/p>\n

<\/a><\/p>\n

Z-axis coordinates of the sheets mentioned above are all zero.<\/p>\n

Additionally, I’d like to ask how to implement a “merge-like” operation in HFSS.<\/p>\n

Looking forward to hearing back from the engineers~<\/p>\n","protected":false},"template":"","class_list":["post-359955","topic","type-topic","status-closed","hentry","topic-tag-ansys-hfss","topic-tag-boolean-error-1","topic-tag-bug-report"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["342715","28551"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1781"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1712051191:294293"],"_bbp_topic_id":["359955"],"_bbp_forum_id":["27793"],"_bbp_engagement":["28551","342715"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["362489"],"_bbp_last_active_id":["362489"],"_bbp_last_active_time":["2024-04-16 14:01:07"]},"test":"scm17mails-tsinghua-edu-cn"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/359955","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/359955\/revisions"}],"predecessor-version":[{"id":359957,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/359955\/revisions\/359957"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=359955"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
