I&#039;m using 2D axis symmetry. I have written a user sub routine so that any SPH particles that pass through a numerical fence at the boundary of my target get their data read into a .dat file. This allows me to extract individual x-momentum data and do my calculations. I&#039;m wondering if Autodyn takes into account the fact that I am using 2D axis symmetry or do I need to invert all of my results I get to cover the results in the negative side of the Y-axis?<\/p>\n<p><a class=\"atMention\" data-username=\"cxquan\" data-userid=\"3901\" href=\"https:\/\/forum.webdevonline.net\/profile\/cxquan\">@cxquan<\/a> any idea?<\/p>\n<p>Thanks<\/p>\n","protected":false},"template":"","class_list":["post-163091","topic","type-topic","status-closed","hentry","topic-tag-2d","topic-tag-2d-axisymmetrical","topic-tag-autodyn","topic-tag-hvi-1","topic-tag-sph"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["621"],"_bbp_likes_count":["0"],"_bbp_subscription":["232438"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["163091"],"_bbp_forum_id":["27814"],"_bbp_engagement":["83","185913"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["194815"],"_bbp_last_active_id":["194815"],"_bbp_last_active_time":["2021-10-26 12:01:39"]},"test":"conorryan98"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/163091","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\/163091\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=163091"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
