I need help about the following question:

when I run a piping model and I want to check if there is not any overstressed points, I pick on the Overstressed points Icon and an advisory message appears: "no overstressed poins, or no allowables", but when I see the stress results for each load case, i can find many elements that are overstressed. Why when i pick on the overstressed points icon does not appear any warning message saying that really there are overstressed points in the model???

other question: why in the operation load case there is not code compliance checking?

Thanks.
