I have till the mesh and I need to do the set up. Now, I have a couple of questions: I see&nbsp; fluid zone : so here I should define my sliding mesh : I chose laufrad (wheel) only.? The second question: There is mesh interface ,when I check them I see no pitch scale ! if some one could help me what is no pitch scale ? and why it is between impeller and volute?&nbsp; and there is another one (nps2) between impeller and spiral ?&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-371786","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["134.147.24.44"],"_bbp_subscription":["349458","199"],"_btv_view_count":["96"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["371786"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","349458"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["371875"],"_bbp_last_active_id":["371875"],"_bbp_last_active_time":["2024-07-15 10:43:24"]},"test":"mohamed-faramawyelmalahruhr-uni-bochum-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/371786","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/371786\/revisions"}],"predecessor-version":[{"id":371788,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/371786\/revisions\/371788"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=371786"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
