Why do I always get this kind of warning and error when I try to simulate my geometry with a lower mesh size? The simulation was successful for a 10mm mesh size but resulted in an error with a 5mm mesh size. I tried running it using different cores but got the same error.

Is RAM capacity the issue, or are there any configurations within Ansys that I need to adjust, such as GPU usage or other settings? Or the ratio of Ram and mesh size if there is one? Please see the attached image Thanks

Hello,

As per the message you will need to reduce the model size. You can refer to following thread as well: Increased RAM, but still says insufficient memory

Under Analysis Settings, try changing the Solver to Iterative, which requires less RAM than the Direct Sparse solver.  However, your model may contain elements that can't be solved with an Iterative solver.  Read the solve.out file. If it was incompatible, you will see a message that says it is automatically switching to the Direct Sparse solver.
