Phast now allows for more nuanced weather configurations. Instead of a single wind speed, define that represent the specific atmospheric stability classes (Pasquill-Gifford) and humidity levels of your site location. Material Properties

View "Side View" and "Plan View" of clouds, or "Radiation vs. Distance" plots.

Represented by the Lower Flammable Limit (LFL) cloud footprint. Explosion Modeling (VCE) dnv phast tutorial updated

Modeled for immediate ignition of high-pressure gas leaks.

Modern Phast integrates GIS capabilities more deeply. You can now import high-resolution satellite imagery or CAD site plans to visualize hazard contours directly over your facility layout. 2. Setting Up Global Data Phast now allows for more nuanced weather configurations

Once the dispersion is modeled, Phast evaluates the thermal and overpressure consequences. Fire Modeling

The latest versions of Phast have transitioned toward a more intuitive, ribbon-based interface. Distance" plots

Export hazard contours (isopleths) as Shapefiles or KML files for use in ArcGIS or Google Earth.
