Comparing Stress Values with Non-Uniform Mesh Sizes

Hello, everyone

I have two models. One, derived from experimental data, uses a 0.1mm mesh for static analysis. Stress singularities arise near the concentrated load application point. My current benchmark is the stress value three rows of elements away from the singularity. I want to utilize this value as a reference for future simulations, to evaluate potential risks in a second model. However, the second model contains small geometrical features (less than 0.1mm), requiring a finer mesh (smaller than 0.1mm) in those areas. How should I select a comparable stress value from the second model’s analysis to compare with my established benchmark? My key question is, how to select meaningful stress values for comparison when mesh sizes differ significantly due to localized geometrical details in a model?

Any experience or suggestions would be greatly appreciated.
