I am using CASAR II to determine the stress analysis of a 33km pipeline from one flowstation to another.
The design parameter are: Design pressure 100bar, operating pressure 70bar, design temp 60 deg., operating temp 35 deg, API 5L X52 Pipe, Nominal pipe size 6", sch. 120,.

I want to know how to use Caesar II in modelling from piping to pipeline.i.e from the flowstation to the undergound pipeline.
