What I need, is the value of the strain along a particular path inside the body, which I defined with Construction Geometry. Due to the rubber-like properties of the material, the body experience large deformations, so that the final configuration of the path I defined is very far from the initial one. The path AB is a line. A coordinate system is defined with the origin O set in A and Z-axis pointing to B. What I need, is the strain e_z in the direction of the path (tangent n), point by point. I cannot probe the strain refering to the Global Coordinate System, as shown below (picture on the left). So I tried to align before the analysis the z-axis of the elements in the direction of the path, so that I could refer to the Solution Coordinate System. Nevertheless, the local CS of the elements are not supposed to remain tangent to the path after the deformation, so I am not sure if can rely on this solution (pic on the right).<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/1131407f-5e11-479c-9072-aab800d842d9\/4fa44271-6a64-4c71-85d9-aafe008b7229_6-fea-lap3.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>Is there a way to probe the elastic strain along the path along the tangent n point by point?<\/p>\n<p><\/p>\n<p>Thank you!<\/p>\n","protected":false},"template":"","class_list":["post-38812","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["10990"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1110"],"_bbp_subscription":["242472"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["38812"],"_bbp_forum_id":["27791"],"_bbp_engagement":["897","168014"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["98070"],"_bbp_last_active_id":["98070"],"_bbp_last_active_time":["2019-11-07 20:01:32"]},"test":"tbau"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/38812","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\/38812\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=38812"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
