However, since the geometry of the system is a thin laminate, I would like to define only the constants E11, E22, v12, and G12. I don&#8217;t know the other constants in the Z direction (as they are not of interest to me), but they are required to complete the material definition.&lt;\/p&gt;&lt;p&gt;Is there a way to overcome this problem?&lt;\/p&gt;&lt;p&gt;I would also like to add the number of layers of the material and the fiber orientation angle, information that I can&#8217;t find in the material definition window.&lt;\/p&gt;&lt;p&gt;Any suggestions on how to proceed?&lt;\/p&gt;&lt;p&gt;Thank you very much.&lt;\/p&gt;&lt;p&gt;Andrea&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-406227","topic","type-topic","status-answered","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["406227"],"_bbp_subscription":["505240","58821","240"],"_bbp_author_ip":["2001:b07:646f:4af:1455:ed96:d60c:723f"],"_bbp_last_reply_id":["406497"],"_bbp_last_active_id":["406497"],"_bbp_last_active_time":["2025-01-21 17:04:42"],"_bbp_reply_count":["4"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["3"],"_bbp_engagement":["505240","58821","240"],"_btv_view_count":["382"],"_bbp_topic_status":["answered"],"_edit_last":["505240"],"_bbp_revision_log":["a:1:{i:406229;a:2:{s:6:\"author\";i:505240;s:6:\"reason\";s:0:\"\";}}"]},"test":"andreavincenzo-denunziounisalento-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/406227","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/406227\/revisions"}],"predecessor-version":[{"id":406229,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/406227\/revisions\/406229"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=406227"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
