AutoPSA and CAESAR II

CAESAR II is generally used to calculate the four main pipelines; it can determine the displacement values at any node of the pipelines. It is more professional than Autopsa, as it allows for the consideration of both wind loads and seismic loads. AutoPSA can only output the displacement values and loads of the support points; for pipes other than the four major types, PSA calculation is sufficient.

Does anyone have the CAESARII 5.1 version of the software?

The eMule client for CAESARII version 5.1 is cracked! However, it doesn’t work on some dual-core systems.

AutoPSA can be used on dual-core machines

The CAESARII software is a widely used tool these days, primarily employed for stress analysis of heat pipes. Its features (as summarized by me) include: an English interface, compliance with ASME standards, formatted input options, simple operation, an intuitive interface, easy parameter modification, error-checking functions, user-friendly input for operating conditions, clear and concise calculation results, convenient output of those results, easy selection of spring supports, and the ability to perform primary stress checks due to wind loads, etc. I have never used AutoPSA, so I can’t provide a review.

On May 9, 2011, in Changsha, Hunan, Changsha UESOFT Software Development Co., Ltd. announced that the PDMS stress analysis data interface program UE-PSI1.0 has been released today. The UE-PSI1.0 program was planned starting in October 2010; after 5 months of development by the stress analysis interface team, it entered the beta testing phase at the beginning of March. After the release of the version on April 21, it sparked widespread interest among users in industries such as petrochemicals and chemicals. UE-PSI1.0 is an important milestone for the programs related to the AVEVA PDMS platform developed by UESOFT. In June 2002, UESOFT developed an interface with PDMS’ support and hanger software in UESoft AutoPHS3.1, and in 2007 it created a PDMS database interface in AutoPDMS8.0. External users can download a trial version from the company’s website. Chen Bailian, project manager of the UE-PSI1.0 stress analysis interface program, explained that many clients wish for Changsha UEasy Software Development Co., Ltd. (UESOFT) to provide an interface from PDMS to the pipeline stress analysis programs CAESARII or AutoPSA. After performing a simple installation and configuration of UE-PSI1.0, once you enter AVEVA PDMS, you can see the menu for UE-PSI1.0. The designers use AVEVA PDMS to carry out piping layout, and then employ the UE-PSI1.0 program to convert the pipeline model data from AVEVA PDMS into a format that can be recognized by CAESARII and AutoPSA, thereby avoiding the need to enter data repeatedly in the stress analysis software. Tests have shown that UE-PSI1.0 can be used in AVEVA PDMS 11.5/11.6; customers have also reported that UE-PSI1.0 was successfully installed and run in AVEVA PDMS 12.0. The stress analysis data exported by UE-PSI1.0 is in a format suitable for use with CAESARII 4.5/5.1/5.2 and AutoPSA 8.0. The UE-PSI program also needs to be continuously improved based on user feedback. UESOFT developed UE-PSI1.0 using PML (Programmable Macro Language), the built-in secondary development language of AVEVA PDMS, and Microsoft VC++6.0. Background on the PDMS and stress analysis data interface program: AVEVA PDMS in the UK is a 3D factory design management system software that holds an important position in the field of digital factory design, and it has many users in China’s chemical, petrochemical, thermal power, nuclear power, and other industries. AVEVA PDMS allows multiple users to collaboratively design 3D geometric models of various components in digital factories, such as equipment, pipes, pipe supports and hangers, HVAC systems, cable trays, and building structures, detect collisions, and generate engineering drawings. AVEVA PDMS provides its own stress analysis interface that allows users to export pipeline layout data in an intermediate file format (.cii format) recognizable by the pipeline stress analysis program CAESARII, thereby reducing the amount of data entry work required for pipeline stress analysis. The China PDMS Power Industry Users Group (PUCG) has developed a stress analysis interface using PML, which allows users to export pipeline layout data in a file format (.txt) that can be recognized by the pipeline stress analysis program GLIF. In April 2011, UESOFT developed the UE-PSI1.0 data interface program for stress analysis in AVEVA PDMS. The download address for the UE-PSI1.0 data interface program for Easy PDMS stress analysis is http://www.uesoft.com/bbs7/dispbbs.asp?boardid=119&id=15493&star=1&page=1.

CaesarII is still more widely used; it is employed by major design institutes in China as well as some smaller ones, and there are people available to discuss any issues that arise during its use.

In the power industry, it is generally necessary to fill out a detailed list of supports and hangers, with this list indicating the displacement values and loads at each support point. It is not yet clear how C2 can achieve this functionality, that is, to display only the loads and displacements of the support points and the connection nozzles
