PASS/NOZZLE-FEM V3.5: Finite Element Analysis for Pressure Vessel & Piping

PASS/NOZZLE-FEM V3.5 is a specialized finite element analysis (FEM) software for calculating stress, strength, and flexibility of nozzle-to-shell junctions in pressure vessels and piping systems . Released in June 2024, this version introduces multi-nozzle analysis, new structural attachment types, and updated code compliance .

Key New Features in V3.5

Multiple Nozzle & Attachment Analysis

• Multi-Nozzle Support: Add and analyze multiple nozzles or structural attachments on shells, heads, or bends in a single model

• New Attachment Types: "Plate" and "Two plates" options for structural attachment modeling

• Enhanced Visualization: Preview model with loads and boundary conditions; launch post-processor directly from UI

Code Compliance Updates
