Initially I had some issues compiling the solver with the Makefile, but after adding some lines to the LIBS variable in the Makefile, I was able to compile something. However, when trying to use the file made with the Makefile, with LSrun, I get a license error.&lt;\/p&gt;&lt;p&gt;<a href=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/05\/25-05-2026-1779748651-mceclip0.png\"><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/05\/25-05-2026-1779748651-mceclip0.png\" \/><\/a>&lt;\/p&gt;&lt;p&gt;I tried some of the suggested solutions from previous posts, such as:&lt;\/p&gt;&lt;p&gt;export ANSYSLMD_LICENSE_FILE=127.0.0.1&lt;\/p&gt;&lt;p&gt;env ANSYSLMD_LICENSE_FILE=1055@127.0.0.1&lt;\/p&gt;&lt;p&gt;In the lsout file, it says &#8220;license option:check ansys licenses only&#8221; at the top. I am using the usermat version of R13.1 mpp double precision. I also saw an &#8220;ansyscl&#8221; file was mentioned. If this is needed, where would it be located when downloading the compressed folder? Is it supposed to be inside the compressed folder? I am unable to find file. Also looking in the license tab of LSrun shows licences are active and are waiting to be used.&lt;\/p&gt;&lt;p&gt;Best,&lt;\/p&gt;&lt;p&gt;K&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-458865","topic","type-topic","status-publish","hentry","topic-tag-lsdyna","topic-tag-lsdynalstccentoslinux-1","topic-tag-lsrunlicenseerror-1","topic-tag-usermat"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27814"],"_bbp_topic_id":["458865"],"_bbp_subscription":["659990","523"],"_bbp_author_ip":["50.222.127.226"],"_bbp_last_reply_id":["458882"],"_bbp_last_active_id":["458882"],"_bbp_last_active_time":["2026-05-26 22:13:45"],"_bbp_reply_count":["6"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["659990","523"],"_btv_view_count":["50"],"_bbp_topic_status":["unanswered"]},"test":"kshi84gatech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/458865","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\/458865\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=458865"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
