Over the past few weeks I managed to get better MPM model results using a smaller time step. I am testing MPM models with hexahedral meshes at the moment and the results are also good. In relation to simulating a dropping object using moving meshes, is there literature or any tutorial with advice on setting up 3D dynamic mesh 6dof simulations that don&rsquo;t use the VOF multiphase model and involve geometries moving (ideally falling) in a viscous fluid? My interest is primarily in relation to hexahedral meshes, and so far I understand that hexahedral meshes can only be layered and\/or smoothed, but not remeshed. Thanks for your time.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-288808","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/288808","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/288808\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=288808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
