<p><p>Hello everyone,<\/p><p>I normally use Ansys Workbench R1 2023 and Optislang R1 2023 to run some optimisation studies.<\/p><p>Last week, I launched a sensitivity study in Optislang that included running the Workbench in batch mode (I have done this before and never had problems). When I checked the simulations the next morning optislang had closed and trying to reopen the project didn’t work. I tried to open other project but with no success, even when trying to open a blank project there was just a blank window that never loads:<\/p><p><\/p><p>I uninstalled the entire Ansys package and reinstalled it again. This time I installed the R1 2024 version and it seemed to be working. Sometimes it won’t load the projects and sometimes it will, so I thought it wasn’t too bad. However then I realised that there are issues with the license and I can only open the projects in view-only mode:<\/p><p><\/p><p>I don’t know why the license is missing and there are no explanations of that error. <\/p><p>I checked the license manager and seems fine:<\/p><p><\/p><p> <\/p><p>I then reinstall the R1 2023 version and surprisingly found the same error with the license.<\/p><p><span style=”font-size: 18.6667px;”>I have contacted my department to check that everything is fine with the license but <\/span>I am pretty sure it is (I can use Fluent and Workbench without problems) so I am really wondering what’s wrong with optislang.<\/p><p>Does anybody know how to solve this problem? I have already uninstalled and reinstalled everything twice (both for the R1 2024 and R1 2023) and I really don’t know what to do.<\/p><p>Thank you very much in advance.<\/p><\/p><\/p>\n","protected":false},"template":"","class_list":["post-427408","topic","type-topic","status-closed","hentry","topic-tag-buglicensingerror-1","topic-tag-ansys-issues-1","topic-tag-optislang"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27796"],"_bbp_topic_id":["427408"],"_bbp_subscription":["261033","16547"],"_bbp_author_ip":["194.82.242.11"],"_bbp_last_reply_id":["428573"],"_bbp_last_active_id":["428573"],"_bbp_last_active_time":["2025-04-10 14:36:06"],"_bbp_reply_count":["13"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["261033","16547"],"_btv_view_count":["363"],"_bbp_topic_status":["answered"],"_edit_last":["261033"],"_bbp_status":["answered"]},"test":"3831efb3fcdd393755e6579984b42ad9059c6826"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/427408","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\/427408\/revisions"}],"predecessor-version":[{"id":434085,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/427408\/revisions\/434085"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=427408"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
