The new "Beach" model provides detailed simulation for both onshore and offshore releases, expanding Phast's applicability across different environments.
A typical updated tutorial should follow this logical sequence:
To master the latest version of DNV Phast—version 9.0—it is essential to understand the new interface, enhanced modeling for energy transition materials, and expanded CFD capabilities.
Phast's integrated model automatically selects appropriate consequence models based on your scenario. Once configured, running calculations is straightforward: select the relevant folder in the Models tab and click "Run" in the Home tab. The software processes calculations for each scenario and weather condition, showing progress as it works through each combination.

For atmospheric dispersion, Phast calculates how the plume spreads.
Predicts overpressure blast waves using multi-energy or BST (Baker-Strehlow-Tang) methodologies. The Phast Workflow
Drag and drop your scenarios onto their exact geographic coordinates on the map.
Phast (Process Hazard Analysis Software Tool) examines the progress of a potential incident from the initial release of a hazardous material to its far-field effects. The new "Beach" model provides detailed simulation for
Phast includes a comprehensive, built-in chemical database. Search for and add it to your project’s active material list.
The recent release focuses on accuracy and the energy transition:
Track how the chemical concentration dilutes (in ppm or % volume) as the cloud moves further away from the leak source.

Upon launching, users now begin in the "Study Manager." Instead of juggling separate files for discharge, dispersion, and fire, all scenarios are nested under a single study. The key change is the Scenario Tree on the left panel. Right-clicking allows users to duplicate, modify, or re-run scenarios instantly. For a new user, the first step is to define the Material Database —which now includes over 2,000 components, including real fluid mixtures and hydrates, updated to API and AIChE standards.
Following the introductory e‑learning, the course provides a deeper dive. This instructor‑led course (available both in person and online) covers all areas of consequence modelling: discharge, dispersion, pool formation and evaporation, fires, explosions, and toxic effects. Through extensive hands‑on workshops, participants learn to create a range of scenarios from scratch, model the full progression of a hazardous release, and interpret results in tabular, graphical, and map formats. For experienced users seeking specialised knowledge, DNV offers advanced modules including the SA‑03/05 Phast advanced modelling course, the SA‑18 Phast CFD add‑ons training (covering the CFD modelling of fires and dispersion), and Phast 3D Explosions extension training.
This is the core of your analysis. You'll specify:
