Rick,

The nozzle displaced in three directions but in only one operating temperature. It involves three direction during expansion because of its location with respect to centerline and anchor location of vessel it is attached to. So my point is that if you are giving dy, dx and dz under T1 in your diplacement entry window ( say rx, ry and rz is rigid) then how come their load case contains only one line having D1. I don't know if it is right. I thought that having these three displacements you would necesarily create load cases in three lines for operating say:
W+P1+T1+D1+H (say WITH HGR) OPE
W+P1+T1+D2+H OPE
W+P1+T1+D3+H OPE
When I saw their load cases without D2 and D3 at all in any line, does it make no difference? Did they do it becuase the displacenments occured at only operating temperature? If it so why then do you neeed to plug in displacement on the other two direction? So, are they right? Thanks.
