Intergraph CAESAR II is a complete pipe stress analysis software program which has become the standard for pipe stress analysis. CAESAR II stress analysis software is used extensively and worldwide by both global and local engineering organisations.

The input graphics model of CAESAR II facilitates intuitive pipe stress analysis modelling. A CAESAR II stress analysis shows piping system flexibility, plus any areas of concern. Pipe stress analysis results, in the form of displacements, loads and stresses, are compared with international piping standards and piping codes.

CAESAR II provides for the static and dynamic analysis of piping systems. Calculation capabilities include:

• fibre reinforced plastic
• buried piping
• wind, wave and earthquake loading
• expansion joints
• valves, flanges and vessel nozzles
• piping components
• nozzle flexibilities

CAESAR II models structural steel, and provides spectrum and time history analysis and automatic spring sizing.

CAESAR II includes an extensive materials database showing allowable stresses for ass commonly used piping codes, plus databases for valves, flanges and expansion joints.

CAESAR II has a bi-directional link with CADWorx Plant, Intergraph's comprehensive 3D piping and plant design software. Use Intergraph's CAESAR II and CADWorx together to achieve significant productivity gains such as CAESAR II data producing piping isometrics in CADWorx.

AFT Impulse is pipe flow calculation software that addresses the effects of waterhammer and other undesirable transients in piping systems. AFT Impulse transient force files can be imported into CAESAR II for Dynamic Time History and Response Spectrum analysis.

CAESAR II files may be imported into FE/Pipe's beam modeller for finite element analysis with shell or brick models.

CAESAR II is developed by Intergraph's renowned mechanical engineering experts. CAESAR II software is tested using stringent quality assurance standards and is fully supported by a trained team at Fern, backed up by Intergraph's software engineering programmers.

Additions and changes in CAESAR II version 5.20:

• Added ISO-14692 Code for FRP systems.
• Added a Loop Optimization Wizard to assist in expansion loop design.
• The Buried Pipe Modeller now supports the American LifeLines Alliance as a second soil stiffness method.
• Added the Mexican Seismic Code to the Dynamic Input module for the automatic generation of response spectra.
• Added a static seismic wizard to assist in computing G factors for ASCE, NBC, and CFE.
• Added (10) additional wind codes to the Static Load setup.
• Increased the permitted number of static load cases has been increased from 99 to 999.
• Modified the valve/flange insertion routine to cut back the straight pipe length if necessary.
• Added a number of drop lists to the Piping Input Spreadsheet to assist with input specification. These drop lists appear on the bend radius and insulation density fields.
• Streamlined Spring Hanger Table definition through the addition of three checkboxes for: cold load design, extended range springs, and centered hot load.
• Flange Symbols are now drawn on the piping elements if flange ratings have been requested.
• Revised the following piping codes due to code changes: B31.1, B31.8, GPTC/Z380, ASME NC, ASME ND.
• Moved User writeable subdirectories from below \caesarii to the %allusersprofile area.
• Added automatic e-mail generation for Technical Support issues.
• Improved the File Open dialog to permit the roll-back to earlier revisions of the (piping) input.
• Added an export option for Static Output data - export to MS Excel. This is raw data only to improve export speed.

CAESAR II Version 5.20 - Technical Changes

The following changes may affect the numeric results:

• Corrected the load vector for expansion joint bellows elements for fluid weight and insulation loads. (Corrected in Ver 5.10, 080207 build.)
• Modified the way allowable stresses are selected (from previous elements) for non-defined materials in the material database. (Modified in Ver 5.10, 080207 build.)
• Changed the values displayed in the stress report to Code components instead of mechanical stress values. This change can affect axial, bending, torsional, and hoop stress values. The code and allowable stress values are unaffected by this change. (This change is optional.)
• Corrected the axial stress determination for PD-8010-2. (Corrected in Ver 5.10, 080207 build.)
• B31.8 2007 introduced a second equation (in Chapter VIII) for the determination of the hoop stress.
• The first (older) equation is used unless the hoop stress configuration switch is set to Lame’s Equation.
• B31.8 2007 also changed the exponent in the SIF equation for concentric reducers.
• Corrected material database entries for B165 N04400 for B31.3 and All Codes.
• Corrected the determination of referenced temperature vectors in combination load cases, necessary to compute the Eh/Ec ratio for CODETI and EN-13480.

Question	Why does CAESAR II version 5.20 throw an error message "Feature not found, or NetHL licenses all in use H0031" on program startup, but CAESAR II 4.5 works fine with local green USB ESL HASP key?
Answer	CAESAR II 5.20 requires local and Network USB HASP keys to have a firmware version of 3.21. The error number H0031 indicates that the current firmware version of your local HASP key is 2.16 which can be verified by visiting HASP Admin Control Center web page.  Click on HASP keys under Administration options menu and check the firmware version of your dongle. Please follow these simple instructions to apply the firmware update: Go to the \Assidrv directory located under the CAESAR II 5.20 program directory at C:\Program Files\Intergraph\CAESAR II 5.20\Assidrv and run the executable Firmwareupdate.exe and click on apply button. Please ensure that this is the only HASP key attached to your PC. Disconnect any USB memory/flash drives prior to applying the firmware update. The HASP key red light will blink for several seconds and then it will become steady. Now close the firmware utility and revisit the HASP web page to check and confirm the firmware version update to version 3.21. CAESAR II 5.20 program should run correctly after this firmware update.
Question	We can not find 132 column report selection in CAESAR II 5.20 as there is no miscellaneous option check box available in the static output processor. Any idea how can I generate 132 column reports in CAESAR II 5.20?
Answer	The miscellaneous option check box for 132 column report is available in CAESAR II version 4.5 and older programs in the static output processor but in later versions i.e. CAESAR II version 5.0, 5.1 and 5.20, the 132 column report is now known as extended report. See under standard report column where you will find restraint summary extended, stresses extended and code compliance extended reports which are all 132 column reports.
Question	The configuration file is missing after the installing CAESAR II 5.20 on a Windows XP 64 bit platform. Any idea how can I fix this problem?
Answer	This is a known issue in CAESAR II 5.20 release build 093004 which has been addressed in September build 090904. Please download and install this build from Intergraph's web site by visiting the link.
