The upper body represents the sphere. Both bodies are 2D and are meshed with axisymmetric PLANE182 elements. Both bodies were generated with an APDL script, exported to a CDB file and imported in the Ansys Workbench Project. The initial velocity of the sphere is oriented downwards with -0.1 m\/s.<br \/>The problem is, that no contact is detected. The contact tool states that the status is far open, although there is no gap between the sphere and the surface.<br \/>I have already successfully modeled other contact problems in 2D and 3D with the same procedure but without the axisymmetric property. I therefore assume that the problem has something to do with this axisymmetric feature.<br \/>Thank you very much for your help!<\/p>\n","protected":false},"template":"","class_list":["post-46333","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["18516"],"_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":["582"],"_bbp_subscription":["253909"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["46333"],"_bbp_forum_id":["27791"],"_bbp_engagement":["179798"],"_bbp_voice_count":["1"],"_bbp_reply_count":["0"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["46333"],"_bbp_last_active_time":["2020-07-20 14:07:13"]},"test":"tobi"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/46333","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\/46333\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=46333"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
