I&#8217;m fairly new to Fluent and I&#8217;m using Ansys 2025 R1 student version.&lt;\/p&gt;&lt;p&gt;I have everything modeled and set up, but due to the small timestep, it will take very long (in real-time) to run the simulation. Through calculation activities I have it set to autosave every X time steps (shown below). I&#8217;ve used this to model shorter transient flows before. But for this longer simulation, I would like to run it overnight. I tried doing this previously but it stopped and the project became locked. I&#8217;m assuming this was due my computer going to sleep and\/or locking?&lt;\/p&gt;&lt;p&gt;Is there a way to have it continue running and saving without just keeping my computer awake? As well as saving the overall workbench file? I think I just don&#8217;t yet have a good understanding of the autosaving\/output process.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/06\/20-06-2025-1750430442-Screenshot 2025-06-20 104025.png\" alt=\"\" width=\"272\" height=\"337\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-434940","topic","type-topic","status-answered","hentry","topic-tag-autosave-1","topic-tag-files-save","topic-tag-fluent","topic-tag-output-files-and-saving"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["434940"],"_bbp_subscription":["538764","199","240"],"_bbp_author_ip":["128.163.238.85"],"_bbp_last_reply_id":["435280"],"_bbp_last_active_id":["435280"],"_bbp_last_active_time":["2025-06-24 15:28:35"],"_bbp_reply_count":["8"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["3"],"_bbp_engagement":["538764","199","240"],"_btv_view_count":["1431"],"_bbp_topic_status":["answered"]},"test":"jdch232uky-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/434940","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\/434940\/revisions"}],"predecessor-version":[{"id":435284,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/434940\/revisions\/435284"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=434940"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
