Dear PIZZAPIPE,

It's generally to include occasional load in checking nozzle load. For your load case using L1 to L7. Look at your client specification if they provided the nozzle allowable for such size and rating. If it is provided you can add one more load case for simply in checking Lxx = L1+L3+L4+L5+L6+L7) using max operation in load case combination TAB. If this pass no need to check one by one L1 to L7.

But new version of Caesar already provide the max without setting up load case Lxx I mentioned above if your nozzle node is in restraint (let say ANCH) or displacement boundary condition.

But don't ever use combination load cases in checking load. Only native load cases give the real result for force and moment like L1 to L7.
