Hi Shivakumar,
I would suggest that you may need to re arrange the piping in your model.
Another common problem in modelling such nozzles is if you make them absolutely rigid then enomoius loads and moments will arise. If you put the smallest of "gaps" in the restraint the nozzle will behave as it would in practice and accomodate a small amount of strain say .010". You may find that the loading is more realistic.
Try running the model without this restraint and check the strain. WEokr out what leg of the piping is causing the problem and modify the route or support it differently by the use of spring hangars etc.

Dear friends,<BR>
<BR>
I'm doing analysis for piping where pump is getting<BR>
connected at one end. I have fixed the pump nozzle as<BR>
fixed point. Since there was a huge value for moment<BR>
'Mx', I have introduced one Ry, rotational restraint.<BR>
Now all the moment has been transferred to this<BR>
restraint. It is not possible to design the support<BR>
for such a huge moment. Please advise any other method<BR>
to reduce these moments.<BR>
<BR>
Thanks<BR>
