I&#8217;m trying to simulate with a CFD approach the casting of fresh concrete. Inside the material (modelled as a non Newtonian fluid) I need to put randomly the fibers. For this condition I&#8217;ve thought about DEM modelling. I would like to better understand the modelling condition:<\/p>\n<p>-how can I model the flowing of the material (concrete+fibers) from an initial volume, which is located at a certain height, to the formwork below it (with air inside it initially)? There is a condition of falling for a certain distance (no contact between initial volume and formwork) and an impact of the material in a central surface at the top of the formwork .<\/p>\n<p>-for the DEM of the particles, can I use Ansys Rocky (but I suppose that I need a license) or do I need to use a coding file to implement?&nbsp;<\/p>\n<p>Thank to everyone who will help me.<\/p>\n<p>Ivan<\/p>\n","protected":false},"template":"","class_list":["post-373835","topic","type-topic","status-closed","hentry","topic-tag-anysys-licences-1","topic-tag-fluent-cfd-ansys-1","topic-tag-ansys-cfx","topic-tag-cfd-dem","topic-tag-drag-force","topic-tag-fluent","topic-tag-udf"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["440569","56012","199"],"_bbp_author_ip":["176.243.37.99"]," _bbp_last_reply_id":["0"],"_btv_view_count":["302"]," _bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["373835"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","56012","440569"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["374277"],"_bbp_last_active_id":["374277"],"_bbp_last_active_time":["2024-07-30 16:45:58"]},"test":"ivan-beltracchiunibs-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/373835","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\/373835\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=373835"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
