The piston also follows the curved cylinder instead of a crank-slider mechanism. I want to perform a dynamic mesh zone for piston in ANSYS ICE (fluent) in which instead of piston moving in z-axis, it has an angular motion around x-axis but at a distance&nbsp;equal to the&nbsp;radius of piston motion. Picture is attached below for your kind reference. I need to know how to specific the axis of rotation for piston in dynamic mesh. Please help me in the dynamic mesh modelling for the piston motion.<\/span><\/p>\n<p><\/p>\n<p><span style=\"color: #201f1e; font-family: Calibri, sans-serif; font-size: 14.6667px;\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/478e28ab-675e-4534-b1d5-abf800fad5f6\/d6737a11-8363-4199-ba31-abfa009b6c31_capture.jpg?width=690&amp;upscale=false\" alt=\"\" width=\"866\" height=\"404\"><\/span><\/p>\n<p><\/p>\n<p><span style=\"color: #201f1e; font-family: Calibri, sans-serif; font-size: 14.6667px;\"><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/478e28ab-675e-4534-b1d5-abf800fad5f6\/1998c0f3-cd51-4110-a707-abfa009b845e_capture2.jpg?width=690&amp;upscale=false\" alt=\"\"><\/span><\/p>\n","protected":false},"template":"","class_list":["post-46185","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["18367"],"_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":["409"],"_bbp_subscription":["253691"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["46185"],"_bbp_forum_id":["27792"],"_bbp_engagement":["179575"],"_bbp_voice_count":["1"],"_bbp_reply_count":["0"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["46185"],"_bbp_last_active_time":["2020-07-16 09:27:20"]},"test":"geniusjimmy92"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/46185","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\/46185\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=46185"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
