When I use simple triangular mesh everything works fine, but I would like to perform calculation using &laquo;symmetrical&raquo; about the Y axis rectangular (or triangular but symmetrical) mesh. The problem is that cylinder can deviate in X direction and I can&rsquo;t use simple layering option for region below the cylinder. When I try to use the same options as for simple triangular mesh (smoothing and remeshing) I have pretty bad mesh in the end of simulation. I have also tried to&nbsp;use&nbsp;<\/span>&laquo;symmetrical&raquo; triangular mesh, but after first time step mesh below cylinder was remeshed. I think that the main problem in&nbsp;setted&nbsp;skewness, but when I try to reduce it I have message: &#8220;Maximum Cell Skewness outside reasonable limits, using 0.4 instead&#8221;<\/p>\n<p><\/p>\n<p class=\"MsoNormal\" style=\"text-align: justify;\"><span lang=\"EN-US\" style=\"mso-ansi-language: EN-US;\">Can someone help me to find information about appropriate dynamic mesh options for this case?<\/span><\/p>\n<p><\/p>\n<p class=\"MsoNormal\" style=\"text-align: justify;\"><span lang=\"EN-US\" style=\"mso-ansi-language: EN-US;\">Files with &laquo;symmetrical&raquo; mesh are in attachments.<\/span><\/p>\n<p><\/p>\n<p class=\"MsoNormal\" style=\"text-align: justify;\"><span lang=\"EN-US\" style=\"mso-ansi-language: EN-US;\"><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/4841be35-f88b-4ed0-892c-a8c40052519c\/249a246c-6738-4d16-99e4-a8c700817bdd_symmetrical-mesh.jpg?width=690&amp;upscale=false\" alt=\"Symmetrical mesh\"><\/span><\/p>\n","protected":false},"template":"","class_list":["post-29110","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["1277"],"_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","0","0","0","0"],"_btv_view_count":["603"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["29110"],"_bbp_forum_id":["27792"],"_bbp_engagement":["154844","262268"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["58065"],"_bbp_last_active_id":["58065"],"_bbp_last_active_time":["2018-04-20 04:57:33"]},"test":"user-deleted"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/29110","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\/29110\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=29110"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
