RE: signification of SP in Von mises plot

You are using shells or beams, in finite elements, shells/beams have a number of section points, being, points in the (cross) section of the structure. e.g. for a rectangle you have 1 in the center, 4 in each corner, and a number of points in between. Obviously, when you bend or torque a structure, the stress in the section points will all be different.

You can find the numbering of section points in the manual, it depends on the geometry. Which one you should use depends on what you want to find out. If you want a maximum, it should be the max of all 15 SP.
