Dear Michael_Fletcher,

I guess you have not gone through my earlier posts or have some mis understanding about the query.

1.) I want to know weather we can create a common resolution point for a 6 stage compressor. If yes how can we do it and what should that point be?
2.) If not a common resolution point, then should it be modeled as a different piping system with no interaction between any of the stages? If this approach is used for modeling the piping, suction and discharge ends of the pipe connected to the nozzles of the compressors will have to modeled as an anchor point. This will make the system stiff as CAESAR II default value for the anchor is 1*10^12 N/mm. This will result in values of loads at anchor point to be very high and will not satisfy the allowable limits of NEMA sm-23 or API 617 analysis
3.) Please guide elaborately on point 1 and 2 with practically applicable data with supporting document / code / standard
