My question is: How it is possible that i measure 30% less the expected thrust (5.5e-4N) when i&#8217;m using overse mesh with one degree of freedom, reaching also higher rotational velocity (140 rad\/s) with respect to the sliding mesh where i set the inlet velocity as in the overset and I assign a rotation rate&nbsp; (124 rad\/s) to the blade in the cell zone condition panel. When i compute the force in the sliding mesh, it match with what i&#8217;m excepting but in the overset framework a huge error occur.&lt;\/p&gt;&lt;p&gt;I&#8217;ve tried different boundary conditions, always the same error&lt;\/p&gt;&lt;p&gt;Thanks a lot&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-388739","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["193.205.81.18"],"_btv_view_count":["204"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["13659"],"_bbp_topic_id":["388739"],"_bbp_forum_id":["27792"],"_bbp_engagement":["13659","275015"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["389092"],"_bbp_last_active_id":["389092"],"_bbp_last_active_time":["2024-10-10 13:29:38"]},"test":"alberto-lollisantannapisa-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/388739","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\/388739\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=388739"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
