Hello,

Please consider a piping configuration as below.

Vertical pipe connects with a horizontal vessel nozzle.
fluid is water with density of 1000 Kg/cu.m

If we model the system as Anc (with disp.) at vessel nozzle, the anchor forces (especially 'Fy') in SUS load case at Anc node includes the water weight also.
But in reality it willnot be the case.

There are many systems, where pipes with considerable fluid density drops near the vessel by 2 to 4 meters and connects with nozzle.

Can somebody explain how to interprete the result at ANC in such conditions.

Thanks in advance
