You can set a different partitioning method before reading the mesh or case file. If you are using MPICH as the communicator we recommend using the Metis partitioner.  1. Start FLUENT in network parallel with 4 or more processors and plenty of memory. 2. In FLUENT select the &#8220;Parallel&#8221; menu 3. Choose &#8220;Auto Partition&#8221; 4. Unselect &#8220;Case File&#8221; 5. Select &#8220;Metis&#8221; as the partition method 6. Choose OK  You should now be able to load the mesh or case file without memory problems.<\/p>\n","protected":false},"template":"","class_list":["post-161739","topic","type-topic","status-publish","hentry","topic-tag-4424","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-general","topic-tag-general-fluent"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["23.56.168.180"],"_bbp_last_active_time":["1-24-2023  20:20:24"],"_btv_view_count":["2976"],"siebel_km_number":["1191"],"product_version":["16"],"km_published_date":["2005-03-09T17:30:00.000Z"],"family":["Fluid Dynamics"],"application_name":["FLUENT"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/161739","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/161739\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=161739"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
