Here Rocky can not initilize a packed condtion, but rather spaced only. With spheres we can get very dense packed volumes filled.&nbsp;&lt;br&gt;The algorithm will create particles spaced as a virtual sphere around the real shape, this means very far from what we would like to.&lt;br&gt;&lt;br&gt;You could try two ideas:&lt;\/p&gt;&lt;p&gt;1) avoid volume fill and fill a volume in a calculation with an normal inlet.&nbsp; (easier but can take time)&lt;\/p&gt;&lt;p&gt;2) use the volume fill with a reduced size particle (real shape) like 1\/10. And activate the volume change module (can be found in the installation files) to increase the particles during the run.&nbsp;&lt;\/p&gt;&lt;p&gt;The volume increase still need calculation time and some try and error of how fast you can do it to avoid instabilities.&nbsp;&lt;\/p&gt;&lt;p&gt;Best regards&lt;br&gt;Lucas&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-366762","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/366762","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\/366762\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=366762"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
