    AutoPIPE Vs Caesar - User interface

    Applies To
    Product(s): AutoPIPE
    Version(s): V8i
    Environment: N/A
    Area: New Users

    Original Author: Bentley Technical Support Group

    Problem:

    AutoPIPE and Caesar are both 2 iconic programs that perform the same functions; Pipe Stress Analysis based on pipe arrangement, pipe properties, and applied loads. Although these applications have the same end goal, provide stress analysis results, they are different programs with different methodology. This WIKI is to help new users of AutoPIPE that had used Caesar before, but have now migrated to AutoPIPE.   

    Answer:

    Item #1:  1 of 2, most important differences between AutoPIPE & Caesar

    Non-linear Load Sequencing Explained

    Item #2:  2 of 2, most important differences between AutoPIPE & Caesar

    AutoPIPE vs Caesar load combinations

    Item #3:

    C-Node or Connecting Nodes in Caesar

    Item #4:

    Compare AutoPIPE Input Grids with Caesar Spreadsheets

    item #5:

    Dynamic Load questions :

    1. Dynamic load factor

    2. The default % value of critical damping used in Caesar II

    Are answered on the following WIKI page: Dynamic Analysis in AutoPIPE

    Item #6:

    Modeling Support - AutoPIPE

    1. Item #8: Modeling Guide Supports

    2. Item #11: Define a Displacement at a Support

    Are answered on the following WIKI page: Modeling Support - AutoPIPE

    Item #7:

    Error message:

    The load case did not converge. Do you wish to continue iterating?

    Item #8:

    Graphical Point Editing

    Caesar users are used to looking at the model, then reading and entering the point name. In AutoPIPE like CAD use point and click, point names are automatically taken care of.

    Productivity Example - Add a Support

    AutoPIPE Caesar
    1. Click on the Support Point
    2. Select Support Type (Friction & Gaps)
    1. Look at the Graphic Plot & Read Point Name
    2. Go to the data sheet
    3. Click on the Restraint Option
    4. Enter the Point Name
    5. Select Support Type (Friction & Gaps)
    • 2 way gaps permitted all supports
    • Guide - Both Horiz. + Vertical

    • Only 1 gap permitted
    • 2 supports required for Guide + Y

    Item #9:

    Pipe Stress Work involves lots of Iterations

    99 levels of Undo / Redo are available at all times in AutoPIPE such that different support configurations can be tried and if stresses or equipment loads are worse then can easily revert back to some previous state. But in Caesar undo/redo is always lost when exit the INPUT module.

    Alphanumeric node numbering by segments – easy to identify which nodes relate to which parts / line numbers of the model

    Item #10:

    Defining Wind, Wave, and Earthquake Loads

    Go to the Load menu to define them

    Note: Up to 10 (AutoPIPE V8i 09.06.00.xx and lower) or 30 (AutoPIPE V8i 09.06.01.xx and higher) seismic loads are available useful for evaluating +X, -X, +Z, -Z as a minimum for non-linear cases. (Only 3 uniform loads available in Caesar). Similarly up to 10 wind cases available in the one static analysis.

    Item #11:

    Define a displacement at a support

    In AutoPIPE simply assign a displacement at the support for any load case, GR, T1, T2, E1, etc during modelling. Caesar has limitation of defining only 9 displacements which have to be combined in post processing to specific load cases. Insert > Xtra data > imposed support displacement. These can be applied also to anchors but only act in the direction of the restraint.

    item #12:
