    von mises moves around

    Theo Linders

      Hi,

       

      A few months ago i had a strange issue.

      When i used mesh controls to prove convergence suddenly the highest von Mises stress was at a total different

      place, and after a few calculations the peak had been in 3 different places in my assembly.

      Unfortunately i haven't got these files any more but has anyone got an explanation for this??

          Hi Theo,

          That is an odd behavior to see as you reduce mesh element sizes.  I might think that there are 3 locations that could be concentrations of stress and they are all increasing stress values at different rates as you test convergence.  I would probably suggest to look at each location individually for its own convergence and see they settle into particular values or reveal singularities.  It sounds like some more convergence checking would be warranted.
