I am using 2022 R2 Ansys Fluent with the purchase of academic license (or is it called commercial) without the element count limit of 512000. I have searched through the internet and found the most probable reason of that would be unstable network, since Fluent might try updating the data online if connected to internet. I tried running the simulation <strong>without internet connection at the first place<\/strong> yesterday but the error still happened roughly 12 hours after the start. which is about 2\/3 of the total time. I am pretty sure no buttons were clicked during the simulation at all (its 2am) so I am out of ideas what might be the cause.&nbsp;<\/p>\n<p>Some supplementing info:<\/p>\n<ul>\n<li>number of cores used does not exceed that of the computer<\/li>\n<li><span style=\"text-decoration: underline\">the exact same simulations were run <strong>without problem<\/strong> previously, but with lower element counts (now is 2.8mil)<\/span><\/li>\n<li>I am running a RNG k-epsilon model, enhanced wall functions, varying inlet BC, and sliding mesh simulation<\/li>\n<li>Files of &#8220;Error [node 0] [time 9\/9\/22 2:17:19] Abnormal Exit!&#8221; &amp; &#8220;Error [node 999999] [time 9\/9\/22 2:17:19] Abnormal Exit!&#8221; were created, alongside with a &#8220;udfconfig-host.h&#8221; file<\/li>\n<\/ul>\n<p>My second question is that is there a method to recover the data from abnormal exits?
