Dorin,

thank you very much for your very useful information.
I had to study a little bit since you made this post.

I was trying to read the help of Nozzlepro.there is something maybe you can advice also.in Nozzle pro our input loads are limited to Sus/Ope/Occ.how can we convert these loads to ASME Section VIII loads.I mean how should we define Pm,Pl,Pb based on the loads we derive from Ceasar II?Nozzle pro will do it Automatically.but is there anyway we can do it manually?

if we have a piping load on a nozzle,how can we devide it to local membrane or General membrane?

do you have any sample problem of a Nozzle assessment which you have done by Nozzlepro or FEpipe?I appreciate if you can send me a sample problem.
here is my email: khodayark@yahoo.com

many thanks again for your advices,
Khodayar
