Hi,

I want to Analyse a main Header that is blinded at the starting end and drain towards a Tank at the other end. The effluent from the Tank is pumped out to a vessel.
There are other existing Nozzles (3" from Vessels) that are connected to the Main Header

My intention is to put an Anchor with a CNODE on the faces of the Flange since that is a free end .

On the Nozzle of the Pump (Discharge), i intend to put an Anchor on it and on the Nozzle of the existing (3") pipe that tied in into the Header to know the Displacement.

Is this the best way to do Analysis of the aforementioned or is there a better way?

Thanks

At the free end, just leave it alone - don't put any sort of restraint or displacement. "Free" means "free".

Yes you can put an anchor at the discharge nozzle. This will be conservative, but that is ok at this stage.

I'm not sure I understand your comment about the 3" lines. If you put an anchor someplace the displacements will be zero. If you want to find out how much the 3" lines move at the point where they tie into the header, just stub them in using the appropriate "tee" type and run the analysis.
