Richard Ay CTO - Intergraph CAS High Standards Deliver High Quality: Part 2
This is part 2 of an article covering the history of CAESAR II Quality Assurance (QA) efforts. To read part 1 from last month’s newsletter, please click here.
The CAESAR II team’s focus on quality standards speaks for itself. The development of an ASME NQA-1 program, the ISO 9001 audit approval, and 20 years of Stoomwezen certification give further proof of our dedication to quality.
In 1995, at the request of many users, CAESAR II was submitted for approval to Stoomwezen, the Dutch certification authority. Currently a division of Lloyd's Register, Stoomwezen approvals require the analysis of a set of (Stoomwezen) test jobs, and a review of the software documentation. Each major version of CAESAR II released since 1995 has been submitted to Stoomwezen for re-approval, and the authority has accepted every new version.
User requests for a formally recognized QA program prompted the CAESAR II team to implement an NQA-1 quality program in 2011. NQA-1 is an ASME standard of the QA requirements for nuclear facility applications. NQA-1 Subpart 2.7 details specific requirements for computer software expressly addressing configuration management, design, verification, and test control. A properly implemented NQA-1 program for a software product must meet the requirements of Subpart 2.7, in addition to the other NQA-1 requirements for documentation, review, approval, audit, and archival.
In August 2014, the CAESAR II team participated in an ISO 9001 audit. Due to the quality standards already in place for the NQA-1 program, the ISO 9001 auditor accepted the CAESAR II quality program. The Intergraph CAS division was added to the Intergraph ISO registration certificate.
Users can be confident that CAESAR II will remain one of the highest quality software products in the industry.
Components that are part of a piping system, such as valves, flanges, and other elements, are typically much heavier (and stiffer) than the pipe that connects to them. Because of this, CAESAR II groups and refers to these components as rigids.
When solving a 3D beam (simple) bending problem, CAESAR II builds stiffness for pipe and the software calculates stresses based on a simple cylinder, as code standards recommend.
