When I do the stress analysis for CSA piping, I always got a warning message for each node saying "The Z662 piping code has been specified as well as corrosion. Hoop stress is always corroeded, but longitudinal stress is corroded only if the directive ALL_STRESS_CASES_CORRODED is activated in the configuration file." even if I have activated it. Does anybody know how to delete it since there are too many of those?

Thanks,

You're not checking the "Allowable Stress Checkbox" on every element are you?

I checked the "Allowable Stress Checkbox" for all element.

As Rich implies, it is not necessary to check the "Allowable Stress" checkbox for each element. This is a carry forward item, its information automatically carries forward to the next element - just like OD, T1, etc.

You need check this box only when you wish to CHANGE the current values. This is also true with Uniform Load and Wind/Wave Load.

Uncheck a few of these (not the first) and you'll see your warnings reduce.

Sorry I didn't say it clearly. I only checked "Allowable Stress" checkbox for the first element. The following has the stresses automatically. But I still got warnings for each element.
