    Modeling Approaches in AutoPIPE

    Modeling Approaches

    **Attention** Please see the following AutoPIPE help section:
    Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches>

    This help has been provided in order to give users ideas for modeling typical piping arrangements. The steps shown in each example should not be taken as the only method available to create models. In addition, the intent of the examples is to present ways to create adequate models of specific piping components for analytical purposes.       

    a. Anchor h. Bends
    b. Cuts: Cold Spring    i. Flexible Joints 
    c. Frames j. Hangers 
    d. Nozzles   k. Pipes
    e. Reducers   l. Rotating Equipment
    f. Supports  m. Tees 
    g. Valves  n. Vessels 

    Example Systems

    In order to aid users in modeling more complex piping arrangements. Please see the following AutoPIPE help section: 

    Help > Contents> Contents Tab> Modeling Approaches> Example Systems

    Choose from the following topics:

        i. PipeSOIL Interaction: Transition Example

        ii. Water Hammer (Time History) Example

        iii. Steam Relief (Time History) Example

        iv. Harmonic Analysis Example

    Supplemental Documentation

    In addition, with AutoPIPE V8i 09.06.xx.xx and higher, other example systems / tutorials documents can be found under Help> Contents> Contents Tab> Supplemental Documentation> select the document "Supplemental Documentation"  scroll down the document to see a list of PDF files available.
