Hexagon CAESAR II v13


Hexagon CAESAR II  v13

CAESAR II is the world’s most widely used pipe flexibility and stress analysis software, CAESAR II is a complete solution that enables quick and accurate analysis of piping systems subjected to a wide variety of loads, taking into account weight, pressure, thermal, seismic and other static and dynamic conditions, based on user-defined variables and accepted industry guidelines. CAESAR II analyzes piping systems of any size or complexity, whether the need is to design a new system or trouble-shoot an existing one. And, CAESAR II features the only bi-directional link between analysis and CAD design, allowing engineers and designers to easily share information while keeping the drawing and related data in sync.

imilar to all new caesar ii software versions, the latest Caesar II, version 13 will also deliver new and extended capabilities to meet the current market requirements following the latest codes. Some updates are also performed based on the feedback received from the Caesar II software user community.

Changes with respect to SIF calculation / Use of ASME B31J

To calculate the stress intensification factors (i-Factors) and flexibility factors (k-Factors) as per the 2020 editions of the ASME B31.1, B31.3, and B31.9 piping codes, support for ASME B31J – 2017 is added. Now, these factors will be calculated following the philosophy and equations mentioned in the ASME B31J-2017 code.



The ASME B31J SIFs and flexibilities are integrated into the software. The integration is made into static analysis, miscellaneous reports, and a configuration editor. The option to include the default values used in calculations when input values are outside of allowed B3J ranges is also provided. Additionally, the supports for the optional use of B31J with other metallic piping codes are also added.

The outdated calculation modules which were present in earlier versions of Caesar II for the calculation of SIFs at Intersections and Bends are removed and now replaced by the new B31J integration. To help the users regarding some technical aspects of ASME B31J, B31J methods are also added in the technical discussion of the caesar ii help.
