stress of pipe

hi
I model 10 in pipe system the end of pipe one to the nozzle of tank other to suction of pump. what should be consider the end of end of pipe? if I consider anchor is it right? or should be consider it nozzle

thank

The "pump end" you can likely call an anchor. The "tank end" would best be defined as a nozzle with flexibilities.

I might add - calling out anchor and nozzle will define the stiffnesses of these boundary conditions but both may also have associated "operating" displacements. These displacements can be included through the use of displacements on CAESAR II's "CNodes" defined with the restraint/nozzle. Alternatively, the anchor can be replaced with a displacement set.
