Yes, you are right also. My arrow was not against the stress engineers, but piping. They are not to be blamed because of ignorance regarding the stress problems but for the overconfidence that these aspects are only secondary as importance.

I'm not so old (42) and I'm also trained to use computer programs but I 'm not thinking that all is rubbish.

And yes, you're right again then notice that almost nobody is willing to share. But part of this is also because of "we only need some PDS skill"

Best regards,
