Would you like to view stresses at a particular node/element? Or would you like to see a color map cross-section of your model with colors representing the values of a given stress component?
If you selected "S" as a field output option for the elements of interest in your input file, use the rewind/fast forward/back/forward buttons to go to the appropriate output step of interest and make sure that you've chosen to visualize the desired stress component (S11, S22, S33, S12, S23, S13, pressure, Von Mises, etc). Once you've made your view cut you should see a heat map of the desired stress component across elements in that cross section. Good luck!
