| Error Message | Likely Cause | Solution in v9 | | :--- | :--- | :--- | | "Jet exit velocity > sonic" | Normal for gas. Not an error. | Ensure "Choked flow" is checked. | | "Two-phase flashing abort" | Fluid temp higher than boiling point at atmospheric press. | Switch to model. Increase time step to 0.1s. | | "No dispersion contour" | Released mass too low? Or wind speed too high? | Check "Lower cutoff" (LFL). Reduce wind speed to 2 m/s. | | "Explosion overpressure flat" | Used TNT method on non-condensible gas. | Change to Multi-Energy or Baker-Strehlow . |
Below is a structured blog post to help you get started with the updated tutorial. Master the Hazard: An Updated Guide to DNV Phast 9.0
Perfect for safety engineers, risk analysts, and students looking to sharpen their skills.
Always install the Sentinel LDK license client before launching PHAST. The floating license manager is now more robust but requires Admin rights.
