from my wish list for CaesarII:

A check box for activating the LETHAL SERVICE condition and relative calculations/check can be added to the ASME VIII module of CaearII for flange leakage/stress.
With this upgrade the module will be more complete.

ASME VIII div1 app2 references: par. 2-5.3(d) Bsmax check; par.2-6 bolt spacing correction
