      Good morning,

      I have been trying to find the maximum von mises stresses on my design and the safety factor but the more I increase the mesh density, the max stress keep increase exponentially. Is it because of my mesh setting, mesh shape or mesh quality? Thank in advance.

      There is a stress singularity at the fixed support boundary condition.

      See stress singularity on the internet to get some more info on this topic:
