Negative Mesh Convergence is acceptable?

  Good morning,
  I have a question that after doing mesh convergence the number of elements increased and the maximum stress decreases which indicates a negative mesh convergence. Is this stress is acceptable? Can increasing number of elements reduce stress?
  Thank in advance.

  Hi
  
  I would perhaps add a couple of more iterations to see the trend (you have only 2), but I do not see why it could not (obtain lower stress – it is pretty much the same though with ~ 0.1 % ).
  
  All the best
