Explosion Consequence Modeling Software

BREEZE ExDAM® (Explosion Damage & Injury Assessment Model) is a unique, efficient 3D explosion consequence modeling suite that allows users to predict injury and damage resulting from the detonation of high explosive and vapor cloud explosions. BREEZE ExDAM contains the High Explosive Damage Assessment Model (HExDAM) and Vapor Cloud Explosion Damage Assessment Model (VExDAM). These numerical models provide a fast and accurate means to calculate structure damage and personnel injury due to over-pressure (OP), dynamic pressure (DP), and impulse (IP) distributions.

Take a look at the companion product, BREEZE VASDIP, which is designed to compute vulnerability parameters of structures and human body components resulting from explosion impacts for use in BREEZE ExDAM HExDAM and VExDAM modules.

BREEZE ExDAM Key Features

  • Offers streamlined ribbon bar navigation and numerous tools for efficient model set-up and producing detailed results
  • Provide fully 3D interactive interface that pans, zooms, rotates, and handily performs context-driven operations
  • Provides over 200 CAD-like key strokes and shortcuts
  • Present results in 2D/3D graphical and tabular formats
  • Calculate the blast overpressure and dynamic pressure due to high explosives based on TNT equivalency method
  • Calculate the blast overpressure and impulse due to vapor cloud explosions based TNO Multi-energy method
  • Calculate damage to structures and injury to personnel based upon empirical pressure-impulse (P-I) vulnerability data
  • Simulate blast wave propagation around structures and people, where objects closer to the blast act to shield the blast wave from other objects further away
  • Model secondary or sympathetic explosions triggered by damage or failure during primary blast and calculates additive damage/injury
  • Compatible with previous BREEZE HExDAM and BREEZE VExDAM

Who Should Use ExDAM

Failure to identify and mitigate explosion hazards is a persistent cause of industrial accidents, impacting sites ranging from fertilizer storage facilities to refineries. While some explosion consequence assessments are performed to comply with regulatory requirements or industry-specific process safety standards, in many cases the potential for loss of life and property damage is overlooked until a tragedy occurs. Explosion consequence modeling can provide detailed information about the... Learn more


Structure Development

The structure development process begins with creating an ExDAM project file containing the geometry and associated properties of nine data object types:StructuresMapsPeopleLibrary ObjectsPrimary High ExplosivesSecondary High ExplosivesPrimary Vapor CloudsSecondary Vapor CloudsSample Grids Learn more


Model Run and Analysis

With structures, people, explosions, and sample grids defined, the explosion models are then executed to predict structure damage, personnel injury, incident and spatial distributions of over pressure, dynamic pressure, and impulse. The execution of an explosion model is referred to as a model run and each model run produces a results file. High explosive model runs produce '.hxr' results files and vapor cloud explosion model runs produce '.vxr' results files. Learn more


Import Structures with 3D Extend

Modelers can utilize the ExDAM 3D Extend module to accelerate the structure development process and increase productivity and design efficiency. The 3D Extend module was developed to provide time-saving features to help modelers design and analyze the modeling scenario more quickly when investigating explosion impacts. Learn more


Fragmentation Damage Assessment

The flying debris caused by damage to frangible structures can be a significant source of injuries in an explosion. Modelers can now utilize the HExFRAG module of BREEZE ExDAM to model these secondary injuries caused by fragmentation.  HExFRAG uses the explosion modeling results from the HExDAM module to predict injuries caused by flying debris.The HExFRAG module of BREEZE ExDAM was developed based on research conducted by the Department of Energy on fragmentation damage assessment. The... Learn more


ExDAM vs CFD Applications

The two traditional explosion consequence modeling techniques have been:Basic phenomenological models that are very cost-effective but provide very simplistic resultsComputational fluid dynamics (CFD) techniques which provide great detail but are time consuming and can be prohibitively expensiveMany facilities are in need of a detailed explosion consequence modeling analysis to identify and mitigate explosion hazards, but require a moderate approach that can provide detailed damage and injury...

Advanced Science

The HExDAM damage algorithm is correlated against the Southwest Research Institute pressure-impulse diagrams. The VExDAM model employs Van den Berg's TNO multi-energy method, which uses dimensionless curves of overpressure and pulse duration versus range to predict the resultant overpressure and impulse at each structure. The results were validated in a number of technical papers, written by the developer of the HExDAM and VExDAM models and has been used and validated extensively in other... Learn more
