In order to validate my designs numerically I want to use LS dyna to simulate a vehicle impact to said barrier. The main reason for me to use LS-dyna is because the European agency has generic vehicle models I can use which have been independently verified. These models are supplied as K files and have an element count of approximatly 150k nodes. However, as I was looking into the possibilities of Ansys LS-dyna (student license) I noticed the maximum problem size consists of 128k nodes\/elements.&lt;\/p&gt;&lt;p&gt;My question is thus about how this limit is set. Is this problem limit only for running a simulation or &iacute;s it also applied in the pre\/post environment? If this limit is only for the solver itself I should (technically) still be able to use LS-dyna pre\/post in combination with OpenRadios (opensource K-file solver). Can I use LS dyna pre\/post if the problem size exceeds 128k elements or will it cut me off while setting up?&lt;\/p&gt;&lt;p&gt;I look forward to your responses.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-445877","topic","type-topic","status-publish","hentry","topic-tag-student-version"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27814"],"_bbp_topic_id":["445877"],"_bbp_subscription":["377265","13640"],"_bbp_author_ip":["147.161.172.196"],"_bbp_last_reply_id":["445885"],"_bbp_last_active_id":["445885"],"_bbp_last_active_time":["2025-11-07 12:51:14"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["377265","13640"],"_btv_view_count":["162"],"_bbp_topic_status":["unanswered"]},"test":"449055student-fontys-nl"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/445877","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\/445877\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=445877"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
