Hi, 
I’m performing a thermal numerical analysis of a 2 way FSI in Workbench: Fluent (VOF, Dynamic Mesh) + Transient Structural (Elements changed into Type 226) + System Coupling. I am using 46 cores for the analysis in Fluent and 36 cores for the Mechanical APDL.  
After 2 weeks of analysis I am halfway through. The APDL .rst results file takes up 185 GB. However, from a certain Restart Point, saving the results ends with an error in Mechanical APDL:<\/p>\n

\"An<\/p>\n

Then, the solution process freeze. Reverting the analysis to a previous Restart Point also started causing this error. Other analyses on the workstation work fine. In the last correctly saved analysis, the memory allocation was as follows:<\/p>\n

\"DISTRIBUTED<\/p>\n

I am urgently asking for help in finding the cause of the problem. Is the data still recoverable?<\/p>\n","protected":false},"template":"","class_list":["post-276633","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["23.56.168.214"],"_bbp_subscription":["280379","88"],"_btv_view_count":["4267"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["276633"],"_bbp_forum_id":["27796"],"_bbp_engagement":["88","280379"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["278677"],"_bbp_last_active_id":["278677"],"_bbp_last_active_time":["2023-04-10 13:06:00"]},"test":"bkraszewskiimp-gda-pl"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/276633","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\/276633\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=276633"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
