hi.
I have a question about postprocessing.
after analysis, I set the Von mises stress in the surface and max/min postprocessing menu.
so I can see the scale bar and max/min value
but it does not match the value : upper stress scale bar and max. value in the model.
I appreciate to explain why it does not match the value.
and which one is correct?
have a nice day.!

Hi
I would say all and none ;), in 4.1 at least the min max operators have different ways to be evaluated:
node points, integrated points, Lagrange points
The graphs seems to be of the type node points
Then the graphs have a quality property, if you set it to Smoothing "none" you will probably get closer to the min/max operators. Anyhow, when looking at stress, its important to check with no smoothing and norefinement for the resolution, you will then notice that often the oscillations observed are from the smoothing, ort that your meshing is rather too coarse to take good decisions !

Good luck
