I&#8217;m not really interested in the surface itself but of course i have to build a very small size mesh in the near fluid. When i try to start the mesh i have some problems. Is there any way to consider only the mesh in the fluid without generating it also in the surface body? Is there any trick to reduce the size only in that close zone?&lt;\/p&gt;&lt;p&gt;Thank you&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/19-11-2024-1732051674-mceclip0.png\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/19-11-2024-1732051804-mceclip2.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-394397","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["146.241.86.199"],"_btv_view_count":["257"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["199","442260"],"_bbp_topic_id":["394397"],"_bbp_forum_id":["27789"],"_bbp_engagement":["199","442260"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["394552"],"_bbp_last_active_id":["394552"],"_bbp_last_active_time":["2024-11-20 15:14:57"]},"test":"5831b75e374ce16fb046b217384c5667c962b552"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/394397","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\/394397\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=394397"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
