The lattice block is a SOLID BODY with some thickness value (around 0.05 times unit cell length) which I&#039;m trying to compress to very large deformation length (&gt;65% of the block height). Initially I tried with Static Structural but I was unable to converge results.<\/p>\n<p>This made me to consider Explicit Dynamics to go for&#8230; The solving Time issues are more here (Estimated is 20hrs) as I&#039;m not sure how to set Analysis settings and time step values. <\/p>\n<p>The compression rate is 5mm\/min up-to 65% of block height, which is <strong>NOT <\/strong>an impact velocity. <\/p>\n<p>Please help me to reduce solving time.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/159\/ZB0W193TJEEU.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/159\/ZB0W193TJEEU.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-163715","topic","type-topic","status-closed","hentry","topic-tag-compression-test","topic-tag-explicit-dynamics","topic-tag-gyroid-1","topic-tag-lattice","topic-tag-lattice-structure-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["296"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["1098"],"_bbp_subscription":["239361"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["163715"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","239361"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["196903"],"_bbp_last_active_id":["196903"],"_bbp_last_active_time":["2021-11-04 11:09:57"]},"test":"chirag-krishnamurthycollins-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/163715","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\/163715\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=163715"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
