Hi,

In the pump suction line analysis, as per stress philosophy I have to perform nozzle disconnected case (3 mm displacement is allowed). I generally know that in WNC case keeping Anchor (with CNODE) stiffness to zero, we can perform this case. Please correct me if I am wrong.

One more clarification I need is, if we keep the anchor stiffness to zero, it will consider the same for all load cases including WNC case. Is there away that only in WNC case we can keep Anchor stiffness to zero, not effecting the remaining load cases. Please help me.

Thank you in advance
