What could be happening?"},"content":{"rendered":"<p>If  no error is generated by the auto-save, and there is no evidence from the transcript that Fluent has attempted to write the files, then it is possible that the data-frequency is set to flow-time and not time-step:  file auto-save save-data-file-every flow-time  In this scenario, a data-frequency of 5 would mean that the next data-file -write is 5 seconds away.  The best way to verify this is to open the .cas file in a standalone Fluent session after the journal file has been read and inspect the auto-save settings.  Once a .cas file has the flow-time data frequency setting, the journal file will have to first change this setting to time-step and then set the data-frequency:  1. file auto-save save-data-file-every time-step 2. file auto-save data-frequency 5   Doing this in the reverse order may cause the save-data-file-every setting to be ignored or the data-frequency zeroed.  (Both will have the effect of the file not getting written.)<\/p>\n","protected":false},"template":"","class_list":["post-164990","topic","type-topic","status-publish","hentry","topic-tag-2021-r1","topic-tag-fluent","topic-tag-fluent-cfdpost-io","topic-tag-fluid-dynamics","topic-tag-general","topic-tag-na"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["3-15-2023  20:20:11"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["2522"],"siebel_km_number":["2067324"],"product_version":["2021 R1"],"km_published_date":["2022-03-02T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["FLUENT"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164990","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\/164990\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=164990"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
