ASME VIII Div. 2 - Advanced Pressure Vessel Analysis Software

NextGen supports the ASME Section VIII Division 2 standard (Part 4 - Design by Rule) for the advanced design and optimization of pressure vessels.

By utilizing Division 2 rules, the software allows for thickness reduction and material optimization compared to Division 1, while maintaining high safety standards. NextGen handles complex calculations such as fatigue verification, jacketed vessels, and heat exchangers, offering a comprehensive solution for engineers requiring a more analytical approach to design.
