Nozzle Load Issue

Nozzle Load Issue

Nozzle Load Issue

Hello everyone,

I have a stress system in which PSV piping is supported through vessel platform. Please see attached snap. In this stress system, loads at nozzle neck are showing only in Y & z direction forces (FY & FZ), moments (MX). Other force FX and moments MY & MZ are showing as ZERO. Can anybody help me with this? Why is it happening? Is there anything wrong? I checked my input, all the node C-node connections are properly defined.

Piping details: A358 316L CL.1, 10" sch.10S, Ope Temp: 71 deg. F, Max. Design temp.: 150 deg.F, Min. Design Temp.: -20 deg.F

Vessel details: A240 304L, Ope Temp: 71 deg. F, Max. Design temp.: 150 deg.F, Min. Design Temp.: -20 deg.F

Nozzle loads at nozzle neck showing as below:

RE: Nozzle Load Issue

Your plot doesn't show where node 10350 is. If you still have this issue, please open an SR on Smart Support and send in your model.
