The World’s Most Respected Tool for Pipe Stress Analysis


CAESAR II® is the industry standard for pipe stress analysis, letting you build, assess and report on piping systems of any size or complexity in accordance with more than 35 international piping code standards and many environmental and equipment guidelines. Integration with CAD design packages lets you quickly import models, reducing risk for errors and costly iteration time between CAD and Stress Analysis divisions.   


Reduce Manpower Error

Easy to input, display all the data and modify.

Design under international code and standards.

Save time for design and Analysis and be more accurate.

Graphic in program can define for easy to evaluate.

Animate for help to analysis model.

Reduced Modeling Time   

Save time modeling, so you can focus on your stress analysis. Experience superior usability with List Input grids and functionality that lets you work straight from the 3D model. Right-click menus and a functional toolbar layout with customization available lets you work quickly. Integration with CAD design packages lets you quickly import models, reducing risk for errors and costly iteration time between CAD and Stress Analysis divisions.    


Advanced Graphics   

Experience 3D model graphics with fast response times to model actions and intelligent refreshes. The graphics engine provides real-world representation for rigid components, supports and hangers, displacements, rotations, forces, and moments on the piping model.    


Robust Load Case Definitions/Manipulation  

Your customized load case definitions can be imported or exported through an easy to use template. Select to bypass or exclude certain cases from your analysis to speed up analysis time and focus on the conditions of interest. Use the Group Edit view to make quick changes to multiple load cases at once. Use the List view for creating new load cases, filtering and sorting on columns. Automatic renumbering of load cases upon deletion of cases, with easy review of the impacts on combination cases.    


Advanced Analysis and Reporting  

In addition to the evaluation of a piping system’s response to thermal, deadweight, and pressure loads, CAESAR II analyzes the effects of wind, support settlement, seismic, and wave loads. Nonlinear effects such as support lift-off, gap closure, and friction are included. Select the proper springs for supporting systems with large vertical deflections. Analysis accounts for seismic second-degree flexibility and bends plasticization. Dynamic capabilities include modal, harmonic, response spectrum, and time history analysis. Quickly send analysis and time history results to output reports or the file format of your choice (MDB, Excel, Word, etc.).   


Finite Element Analysis  

Access third-party tools for finite element analysis from the main menu, including free access to the recently published ASME B31J-2017 calculations for SIFs and K factors. Quickly send and translate through FEATools™, compare multiple file results, assess the sensitivity of model elements, and evaluate nozzle/branch connections with NozzlePRO™.    

Powerful Integration Capabilities  

CAESAR II offers robust interfacing with CAD-based software, such as CADWorx Plant and Intergraph Smart® suites, using established industry formats (such as PCF and Isogen®). This lets you bring in data from other systems, carry it on to integrating solutions after analysis, and track support details. Import structural models from software such as CADWorx Structure or GT STRUDL®, and account for structural stiffness in the analysis. CAESAR II combined with GT STRUDL lets you share load details post-analysis so stress analysis and civil/structural groups work together without duplicating information and efforts.   


Comprehensive Equipment Analysis  

Associate multiple load conditions and multiple types of equipment in the Equipment Manager, which has connectivity to load cases used in your piping analysis. Experience a user-friendly interface and comprehensive reports. Analyze your critical flanges and flange assemblies against the EN-1591 code standard using a similar easy-touse manager, which automates much of the detailed flange input. Nuclear Industry Compliance CAESAR II complies with ASME NQA-1 quality assurance (QA). Subscribe to the CAESAR II QA and Reporting service to stay fully informed about issues and software changes. This notification service meets U.S. federal requirements 10 CFR Part 50 App. B. and 10 CFR Part 21.
