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.

Model Runtime

Model runtime varies and is mostly dependent on number of structures, subblocks, people, number of explosions, grid resolution, and processor speed. Results can be computed on the order of minutes (usually) to hours (rare).

Results Analysis

After executing model runs, results (i.e. explosion consequences) are then analyzed and documented. Graphical results include 2D/3D images and videos of color-coded damage to structures, injury to personnel, incident and spatial distributions of overpressure and dynamic pressure/impulse using interactive contour planes, iso-surfaces, and volume rendering. Tabular results include a variety of tables to display component and aggregate damage, injury, and incident pressure/impulse to structures and people. The tables are in HTML format which are compatible (via the clipboard or intermediate files) with conventional document composition applications.

Graphical Results

BREEZE ExDAM provides all the tools to visualize the block and sample grid results data within the 3D window. Users can view 3D color-coded damage/injury, overpressure, and impulse in the 3D window; they can also view 2D contouring planes, 3D iso-surface contours, and3D volume rendering. The 3D window provides additional results data selection and display operations. Consequent damage/injury values of 0-100% are also color-coded and categorized as slight, moderate, and severe for each structure/body component.

For example, displayed sample grid contour planes can be selected and interactively dragged left-right and up-down in the 3D window.

Tabular Results

User-defined tables present incident overpressure/impulse and resultant damage/injury values for individual blocks or average values across groups of blocks, segments of structures, or an entire scenario. BREEZE ExDAM provides a number of mechanisms to display, organize, and capture the structure/people block results in HTML table window.
