Hi,

Is your part symmetric in any direction? If yes, maybe you can use planar symmetry to reduce the model size. For your question regarding mesh size, the ideal mesh size depends on various factors such as the complexity of the geometry, the expected gradient of the field variable, and the computational resources available.

Thanks!
