CAESAR II - Pipe Stress AnalysisCOADE (USA) Version 4.5

WINDOWS 2000 PROF/XP, 256+ MB RAM; 64+ MB GRAPHICS MEMORY, 1GHZ + PROCESSOR

CAESAR II is a comprehensive, fully interactive pipe stress analysis program for the static/dynamic analysis ofpiping systems, as well as their supporting structural steelwork, either separately or in combination. Outstandingfeatures of CAESAR include virtually unlimited problem size, on-line help-screen windows, a non-linearout-of-core solver and high resolution colour graphics display. Special features include Water Hammer effect,the dynamic effect of Relief Valve firing, large rotation Rod hangers, a rigorous Underground Pipe Modeler andASME VIII Flange Leakage calculations. Further specialized subroutines cover Nozzle Reinforcement(WRC107), Wind load generation (ANSI A58.1, or user-defined), Rotating Equipment nozzle load calculations(NEMA SM23, API 610, API 617, API661 and HEI), Expansion Joint Rating (EJMA, IWK, Senior Flexonics),Vessel Flexibilities (WRC 297), and Nozzle Flexibilities (PD5500).

The program contains databases for piping materials (including FRP), insulation materials, Spring-Hanger/CanCatalogues (Grinnell, Bergen Paterson, Power Piping, and 7 other manufacturers), Valve and FlangeCatalogues (Crane or "Generic") and Structural Steel databanks (800+ member AISC; German, Australian andSouth African cross sections). CAESAR can model any kind of process or power piping system, will handlestandard and non-standard bends, mitres, jacketed pipe, offsets, flexible vessel nozzles, expansion joints withautomatic pressure thrust, rigid elements and intersections of any kind. Anchors, single- or double-actingorthogonal or skewed restraints, with or without gaps or friction, limit stops, snubbers, tied or connecting nodescan all be modeled. Bourdon effect can be selected optionally and stress intensification factors can be edited.Code compliance is to B31.1/3/4/5/8/11, ASME Class 2/3, BS806, STOOMWEZEN (Dutch), US Navy 505,Z183/4 (Canadian), Swedish, TBK 5-6 (Norwegian), CODETI, and RCCM-D piping codes. In addition WRC 330and Schneider options are available. Recently, the FDBR, BS7159 (FRP materials) and IGE/TD/12 pipingcodes have been added.

Dynamic simulation permits the user to analyse piping and structural models under both imposed harmonicforces or displacements (with optional damping), or earthquake shock including full shock spectrum analysis,with uniform support or independent support excitation. Standard spectra (El Centro and Reg.Guide 1.6) areprovided for shock analysis, or the user can define his own shock spectra (frequency or period, versus force,displacement, velocity or acceleration), which can be written to or read from the hard disk. The sudden ventingof a relief valve can also be modeled by a step function shock load. Natural frequencies can be analysed andmode shapes displayed in animated graphics form.

Data entry may be done by spreadsheet preprocessor or by batch entry mode. Either method is simple andquick. CAESAR has automatic error checking with on-screen messages, notes and warnings being displayed.Immediate graphic display of the isometric view at any stage of data entry, however, virtually eliminates thepossibility of geometric error. High resolution graphics are used for isometrics, 3-D plots and hidden lineremoval. Plotting functions include Zoom, Rotation, Pan, Highlight, Overlays and Range options. Outputgraphics include Overlayed Displaced Shapes, Multicolour Stress and Displacement plots, Restraint/Hangerdisplays and Force/Moment/Stress plots. Graphics files may also be imported or exported via .DXF files to CADpackages like INTERGRAPH, COMPUTERVISION and AutoCADr , for enhancement or dimensioning, and maybe plotted out on any plotter supported by Windows. A fully bi-directional interface is provided for transferringpiping data to/from COADE s CADWorx/Pipe 3D Plant Design software. This interface correctly interpretsCaesar details such as node numbering, elbows, restraints, hanger supports, valves, flanges, etc. and alsopermits stress analysis data to be exported back to the original isometric drawing produced by CADWorx. Thesame pipe and fittings databases are shared between the two programs.

By use of multiple CAESAR windows, the piping plot can be viewed alongside the data input screen. Thegraphics plot can show piping using single line, double line, wire frame, or fully rendered 3D volumetric views.Interactive pan, zoom and rotate allow fast navigation within the plot. CAESAR also has ODBC links to an MSAccess database which allows Caesar input/output data to be written to a central database for customizedoutput reporting and load case comparison. MS Word report output is also available. Both input and outputgraphics are now displayed in 3D using the HOOPS graphics engine which uses OpenGL functions.

CAESAR operates in SI, Imperial, or user-defined units. The user has the option to compose additional "unitfiles" incorporating any combination of input units. Input and output data files can be in any set of units, and maybe converted from one set of units to another very easily. A LAN network version of CAESAR is available.
