However, after receiving the files, the file types were unexpected, and different from what the previous posts and user manual has mentioned.&nbsp;&lt;\/p&gt;&lt;p&gt;They provided me with a folder named &#8220;ls-dyna&#8230;.mpi&#8221; and inside were only a license folder, and 3 executable files named l2a, lstc_client, and ls-dyna&#8230;mpi. Are these the files I should be expecting, and if so, how do I use them?&lt;\/p&gt;&lt;p&gt;Thanks&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-453807","topic","type-topic","status-publish","hentry","topic-tag-user-defined-1","topic-tag-usermat"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27814"],"_bbp_topic_id":["453807"],"_bbp_subscription":["659990","58821"],"_bbp_author_ip":["2610:148:205a:0:852d:8043:ebac:a211"],"_bbp_last_reply_id":["453826"],"_bbp_last_active_id":["453826"],"_bbp_last_active_time":["2026-03-06 07:53:21"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["659990","58821"],"_btv_view_count":["92"],"_bbp_topic_status":["unanswered"]},"test":"kshi84gatech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/453807","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\/453807\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=453807"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
