Like this I could build my grid by modules and change local regions without have to mesh everything again.&nbsp;&lt;\/p&gt;&lt;p&gt;The best example that I could find on the internet similar to that I would like to achieve is a modular meshing methodology by Centaur Meshing: https:\/\/home.centaursoft.com\/software-page\/grid-generator\/key-capabilities\/parts-based\/modular-geometry-and-mesh\/&lt;\/p&gt;&lt;p&gt;As you can see in the image below, two red pipe designs are tested, one is a smooth pipe and the second is a straked pipe. The main grid (in grey) and the blue grid (in blue) are constant as the outer geometry and the second pipe do not change and don&#8217;t need to be remeshed. Only the yellow mesh changes because the pipe is different. Like this you can save a significant amount of time, still have conformal grids and don&#8217;t be affected by solution changes due to the remeshing of the outer zone:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/04\/21-04-2026-1776793056-mceclip0.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-456857","topic","type-topic","status-publish","hentry","topic-tag-fluentmesh-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["456857"],"_bbp_author_ip":["193.125.106.236"],"_bbp_last_reply_id":["457092"],"_bbp_last_active_id":["457092"],"_bbp_last_active_time":["2026-04-25 11:10:20"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["629869","199842"],"_btv_view_count":["108"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["199842","629869"]},"test":"cesarj-95plusgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/456857","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\/456857\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=456857"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
