Is it possible to assign an output color based on a stress value. For example, assign a "red" contour color for stress exceeding the modulus of rupture of a shear wall?
When you run the analysis go to "Shell stress plots/forces" and change the default contour range. You can do that by quickly finding out upper range and lower range of your values, then sets min and max according to the max/min values. hence, you could nicely see the varion in colorful pattern.
