<\/p>\nHello,<\/p>\n
i use ANSYS Fluent 2022 R2 to simulate two rotor blades passing each other closely. 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>\n
Since my computer language is set to german, the message is in german. It says:<\/p>\n
<\/p>\n
“The instruction at … referenced memory at … The read operation could not be executed in memory.<\/p>\n
Click OK to terminate the program. Click Cancel to debug the program.”<\/p>\n
<\/p>\n
Other than that i can find a cortex error file and a general error file in my fluent folder:<\/p>\n
Error [cortex] [time 7\/11\/24 12:40:36] Cortex received a fatal signal (SEGMENTATION VIOLATION).<\/p>\n
Error [node 999999] [time 7\/11\/24 12:40:32] Abnormal Exit!<\/p>\n
<\/p>\n
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>\n
Help here would be really apreaciated. I can provide further information if needed.<\/p>\n
<\/p>\n
With kind regards<\/p>\n
