Here are a few options for a social media post (suitable for LinkedIn, Twitter/X, or a Facebook group), depending on your target audience.

For a jet fire, the old tutorial had you calculate "thermal flux at 5 m."
The new tutorial requires you to define target receptors (e.g., a person, a steel tank). The software now computes Probit equations (for fatality probability) directly on the results tab.
Feature Update: The Pool Fire model now accounts for wind-driven tilt and partial smoke obscuration. The user must input "smoke emissivity" (0.2 for black smoke, 0.9 for clean gas). This affects the radiation received at a distance—a critical factor for emergency response planning.

By lunch, the "Story" feature of the software—a way to sequence events from leak to ignition—was finally clicking. Elias wasn't just looking at data; he was watching a digital twin of a disaster that he now knew exactly how to prevent. He adjusted the isolation valve timing in the model, and the red "lethal zone" on his screen shrank until it cleared the site fence. The Presentation dnv phast tutorial updated

Step 2.2: Inventory & Fluid

Highlights:

Import a .DXF or digital elevation model (DEM) file via the new "Terrain Manager."
Define buildings as solid obstructions. The new Computational Fluid Dynamics (CFD)-informed solver within UDM can now calculate wake regions and canyon effects without requiring a full CFD license.
Run the dispersion. The output now displays concentration isosurfaces that bend around structures.
