I use dynamic meshing with a profile too move my rotor blades. The profile specifies the rotational speed at different time steps. When i run my case it sometimes randomly crashes. Fluent closes mostly without giving any error. I once got this message:<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/14-07-2024-1720950387-mceclip0.png\"><\/p>\n<p>Since my computer language is set to german, the message is in german. It says:<\/p>\n<p>&nbsp;<\/p>\n<p>&#8220;The instruction at &#8230; referenced memory at &#8230; The read operation could not be executed in memory.<\/p>\n<p>Click OK to terminate the program. Click Cancel to debug the program.&#8221;<\/p>\n<p>&nbsp;<\/p>\n<p>Other than that i can find a cortex error file and a general error file in my fluent folder:<\/p>\n<p>Error [cortex] [time 7\/11\/24 12:40:36] Cortex received a fatal signal (SEGMENTATION VIOLATION).<\/p>\n<p>Error [node 999999] [time 7\/11\/24 12:40:32] Abnormal Exit!<\/p>\n<p>&nbsp;<\/p>\n<p>I ran my case on two different computers, both randomly crash on some simulations. If i drasticlly change my element size in my model, the model runs through completly fine, so i do not think my file is fundamentally broken. The crash can be repeated on the exact same time step, either by completly re running the simulation or running from a previous autosave. But again, some models with some meshing variations work.<\/p>\n<p>&nbsp;<\/p>\n<p>Help here would be really apreaciated. I can provide further information if needed.<\/p>\n<p>&nbsp;<\/p>\n<p>With kind regards<\/p>\n<p>Lutz Rohlfing<\/p>\n","protected":false},"template":"","class_list":["post-371808","topic","type-topic","status-closed","hentry","topic-tag-bug","topic-tag-cortex","topic-tag-crash","topic-tag-dynamic-mesh"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["349341","199"],"_bbp_author_ip":["2001:9e8:6819:200:e471:448c:2bee:7dd7"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["384"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["371808"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","349341"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["372065"],"_bbp_last_active_id":["372065"],"_bbp_last_active_time":["2024-07-16 08:41:03"]},"test":"lutz-rohlfinghaw-hamburg-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/371808","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\/371808\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=371808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
