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
