BEE-Line Software's CHARM® software is a Complex Hazardous Air Release Model software program that calculates and predicts the movement and concentration of airborne plumes from released chemicals; thermal radiation impacts from BLEVEs, pool fires, and jet fires; and explosion overpressures from mechanical and vapor cloud explosions. Source terms are calculated from observable data input (e.g. temperature, pressure, hole size, etc.). Results are available in tables, 2D, and 3D graphics.

CHARM comes in two versions. Both are available under a single license. One version is a flat terrain puff model. The other is a complex terrain grid model. The flat terrain version lends itself to fast "what if" analysis. Input parameters can be easily changed with the effects seen quickly. The complex terrain version runs slower than the flat terrain version but is great for detailed analysis of a possible or actual release.

CHARM School is a two day course that covers both versions. The course will cover:

• Release description input
• Meteorological input
• Source term calculation results
• Tables and graphics for impact estimates
• Editor for adding chemicals and maps
• Editor for terrain, particles, chemical reactions, and grids for complex terrain version
• Hands-on exercises
• Time for simulating attendee-supplied releases
