Expanded material databases and updated regulatory consequence criteria. 2. Setting Up Your First Project in Phast
: A major breakthrough. You can now import advanced Computational Fluid Dynamics (CFD) models directly into your quantitative risk analysis, combining high-fidelity modeling with risk calculations.
The core physics engine, known as the , has been updated to handle transient two-phase releases more accurately. Older tutorials emphasized simple liquid or gas holes. The updated tutorial must highlight Phase Change Kinetics . dnv phast tutorial updated
The heart of any Phast model is the discharge calculation. The software determines the rate, phase, and state of the material entering the atmosphere.
For decades, PHAST has been the industry benchmark for consequence modeling—simulating toxic releases, fires, explosions, and dispersion of hazardous materials. However, with frequent updates to the Unified Dispersion Model (UDM), improved user interfaces, and new capabilities in the latest versions (from PHAST 9.x to 10.x), older tutorials often mislead users. You can now import advanced Computational Fluid Dynamics
"The High-Pressure Gas Leak – A Step-by-Step Modern Workflow"
DNV has been on an aggressive development track, introducing significant feature upgrades across recent releases. Understanding these updates is crucial for both new and experienced users, as they fundamentally change how analyses are performed and interpreted. The updated tutorial must highlight Phase Change Kinetics
To make this tutorial truly actionable, you should for a complex, congested site to understand the accuracy difference. If you are interested, I can also:
The Comparison Tool allows you to overlay results from two different scenarios (e.g., before and after installing an emergency shutdown valve) to visually demonstrate risk reduction to stakeholders. Conclusion
: A foundational introduction to Phast, covering all major consequence modeling areas like discharge, dispersion, pool fires, explosions, and toxic effects. It includes extensive hands-on workshops to create scenarios from scratch. Scheduled online sessions (e.g., March 16-19, 2026, from DNV Houston) and in-person sessions (e.g., September 21-23, 2026, in Katy, TX, USA) are available.
Phast presents results in multiple formats. The 3D viewer (enhanced in version 8.6 and later) displays radiation and temperature isosurfaces and isocontours, allowing you to visualise the impact footprint. The Graph Wizard provides 2D plots of concentration vs. downwind distance, thermal radiation vs. distance, and overpressure vs. distance. For overpressure effects, version 9.0 added the ability to produce dynamic pressure exceedance curves , which are essential for designing blast‑resistant structures. The Points of Interest feature allows you to define specific building locations or safety system coordinates and retrieve detailed consequence metrics at those precise points.
