NextGen offers comprehensive coverage of the harmonized standard EN 13445 for the design and verification of unfired pressure vessels.
The software ensures full compliance with the PED Directive (Pressure Equipment Directive), supporting complex calculations such as simplified and detailed fatigue analysis, creep design, and heat exchanger calculation. With NextGen, you can optimize thicknesses and materials, generating calculation reports ready for approval by notified bodies.
