Then, when I performed a calculation by joining all the parts using &#8220;Join&#8221; in the &#8220;Setup&#8221; menu, unintended destruction occurred near the boundary between SPH and FEM. How can I solve this? Do I need to apply contact conditions? If so, how can I do this? I also tried using &#8220;edge packing&#8221; on the target side, but the result was the same.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/23-07-2024-1721730558-Image.png\" alt=\"\" width=\"897\" height=\"532\"><\/p>\n<p>I am using the academic version of Autodyn 19.2.<\/p>\n","protected":false},"template":"","class_list":["post-373206","topic","type-topic","status-closed","hentry","topic-tag-fem","topic-tag-sph"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["439239","83","70001"],"_bbp_author_ip":["150.69.154.36"]," _bbp_last_reply_id":["0"],"_btv_view_count":["559"]," _bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["373206"],"_bbp_forum_id":["27814"],"_bbp_engagement":["83","70001","439239"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["382675"],"_bbp_last_active_id":["382675"],"_bbp_last_active_time":["2024-09-14 06:35:27"]},"test":"satou-taishi422mail-kyutech-jp"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/373206","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\/373206\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=373206"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
