Map results parameters

HenkaCarlsson — Wed, 25 Mar 2015 16:21:16 GMT

I'm analyzing the stresses around a hole in a big steel beam and I have modelled the beam with steel panels. I'm not sure I understand the "map results" parameters tab correctly. I assumed that the "maximum" or "absolute maximum" value would be the maximum of "upper" "middle" or "lower" layer but it doesn't seem so.

In the attached pdf I have marked a point with the principal stress "S1". The "upper" "middle" or "lower" has about the same stress around 350 MPa. But if I choose the maximum value it shows a value of 410 MPa.

Can you explain this to me?

Could you attach the file and indicate at which location (closest node number) to look at?

Look at loadcase ULS component 5 just above node 805 for example. It seems to have something to do with the smoothing. If I use "smoothing within a panel" it fits with the maximum of upper middle or lower layer but if I choose "global smoothing" it's a different value.

You should not use the global smothing for panels not being in the same plane.
