Most of the challenges I faced have been solved, so now I&#039;m looking into the efficiency of the simulation. I&#039;m running my models on a high performance cluster (HPC) in which you would claim multiple nodes if needed. When you claim a node, you&#039;ll get access to all of the 24 processors that the node has. <\/p>\n<p>Since the Fluent and Mechanical problems are solved separately, I would expect that I could use 24 processors for Fluent and 24 processors for Mechanical. When I ran a simulation on my own laptop using 4 processors, I was able to allocate 4 processors for both processes using the following commands (part of my &#039;runFSI.txt&#039; file):<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/SC62ZT2C9SRL\/image.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/SC62ZT2C9SRL\/image.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-51104","topic","type-topic","status-closed","hentry","topic-tag-fluent","topic-tag-fsi","topic-tag-hpc","topic-tag-mechanical-apdl","topic-tag-processors"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23366"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["??^?"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["439"],"_bbp_subscription":["18906"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["51104"],"_bbp_forum_id":["27792"],"_bbp_engagement":["20093","182284"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["138144"],"_bbp_last_active_id":["138144"],"_bbp_last_active_time":["2021-01-08 15:01:03"]},"test":"jfonken"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/51104","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\/51104\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=51104"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
