The typical advice is to essentially double up the load cases and ignore stresses in sections of the model that do not apply to the pipe in question.
can you please explain to me how can i do it?
1)
if i double the load cases (how can i do it?), i always will have the "missing OCC factors"?
2)
how can i set the model to ignore stress for some part of model?
doing so, the OCC factor will appear again?
thank you
