3D Model Editor

A key component of the ExDAM product line is a dramatically improved set of tools for creating 3D models and managing complex model objects. No other graphical interface offers a more complete set of features for designing “life-like” and accurate 3D models.

3D CAD Data Structure and File Formats - The internal and external data structures of Version 7 have been replaced (old .hxd project files can be loaded but are no longer written).

3D CAD-Conventional Structure Creation / Editing - Use image / map and 3D templates to rapidly build complex and highly accurate models.

Interactive Point / Click / Drag Functionality - Rapidly create and edit complex structures using advanced 3D controls and keyboard shortcuts.

Structure Instancing - Structure instancing provides a more useful alternative to simply copying a structure. All edit changes to one instance are applied to all other instances of the structure. For example, define one floor of a building, instance it to make additional floors, and then modify all floors by making changes to only one floor.

Drag / Drop Structure Copying and Instance Copying - Instance structures (or portions of structures) with single click and drag operations.

Rapid Model Object and Materials Properties Editing - Select any combination of structures (e.g., by picking structures in the 3D window or nodes in the data tree) using the conventional Ctrl / Shift keys, and then quickly assign or change their properties (e.g., material, subdivision, etc.) using the selection-sensitive property grid.

Model Object Grouping - Select any combination of model objects (e.g., buildings or people) to create highly organized and named groups within the data tree. With a simple point-and-click or drag-and-drop, you can arrange, group, copy, instance, delete, and rename-model objects in the data tree. 

  Rapid Population and Positioning of Man / Woman / Child Models - In the 3D window and data tree, simply point-and-click or drag-and-drop to add, move, copy, instance, or delete people.

Include / Exclude Structures in Model Runs – Rapidly select model objects to include or exclude from model runs. This feature is a flexible solution when performing iterative analysis over multiple scenarios.

Multiple Over / Dynamic Pressure Grids - Rapidly define 3D calculations grids throughout the modeling scene with flexible XYZ resolutions to maximize visualization of pressure distributions across multiple areas of interest.

Threaded Model Runs and Model Run Queue - ExDAM-V8.0 now allows you to easily set up a batch file to run multiple models in succession. This is a very powerful feature that allows you to schedule multiple runs for processing while you are working on other tasks within the model editor or during non-work hours to maximize available computer resources. Each run is processed in a separate thread, in sequence, while pending runs are placed in a system managed queue.

Optimized Numeric Model  -ExDAM-V8.0 now includes a highly optimized numeric model. Benefits in run times have been demonstrated to be over 10 times faster than the previous version.

Model Runs Saved to ZIP Archive Files - For each model run, all input and results files are packaged into a single .hxz (i.e. zip) archive file which significantly improves file sharing and management. Model runs are displayed in the data tree for rapid viewing, analysis, and documentation. Archive files can be opened to examine the structures, explosions, grids, and results that were used and produced by the model run.

Managed Projects and Modeling Runs – A list of model runs is maintained within the project file and can be edited (e.g., renamed, grouped, or deleted) in the data tree making iterative model runs much easier to manage. Also take advantage of flexible naming conventions for efficient management and reuse of model objects, runs and results files.

Import 2D City Streets and Building Footprints – Rapidly build highly accurate city block-level models by importing street and building footprints from Google Earth™ and Yahoo!® Maps.

  Importing and Display Multiple Base Maps - Rapidly build highly accurate models by using digital architectural drawings, building footprints, and floor plans. ExDAM-V8.0 provides support for importing and displaying the most common graphics image formats, including .jpg, .gif, .tif, .png, and .bmp files. Images support a wide variety of applications including base map templates, building foots, architectural templates, texture mapping/skins. Additionally, a transparency setting may be applied to the imported images in order to display images simultaneously or to view other model attributes underneath the image overlay.

Importing Project Files from Previous Versions - ExDAM-V8.0 has improved project import functionality that supports direct import of previous Version 7 project files. Once imported, users can quickly organize and manage model objects using advanced data tree capabilities including powerful grouping and naming tools.

Displaying, Analyzing, and Reporting Results

To maximize the benefit of your investment in 3D models and project libraries, it is critical that ExDAM-V8.0 provide you with the tools necessary to thoroughly analyze, visualize, and report results. To achieve an in-depth understanding of your modeling results and to effectively present and communicate results across multiple stake holder interests, the BREEZE development team specifically designed the ExDAM-VIII Suite with state-of-the-art 2D and 3D visualization, animation, and reporting tools. Examples of these powerful capabilities include:

  Advanced 3D Display of Structure Damage and Over / Dynamic Pressure Grids - Color or transparency-coded blocks and clipping planes display structure damage and maximum over / dynamic pressures. Use real-time interactive volumes, iso-surfaces, and XYZ contour planes for viewing over / dynamic pressure grids.

Advanced Documentation and Reporting Functions - Use image capture, animation, selection-sensitive text, and HTML-based data tables to show frequency plots of damage and incident pressures to people and structures.

Results Visualization Tools - Include color-coded damage of model structures and people and gridded overpressure and dynamic pressure contours using three powerful viewing options:

• 2D X, Y, Z contour planes
• 3D isosurface contours
• 3D volume rendering

Users have full control over color schemes, contour intervals, min / max levels, and transparency levels. Additionally, model objects such as structures and people can be quickly turned on and off using the active data tree to quickly focus on areas of interest and visualize critical detail as needed.

  Color Shading and Transparency - The algorithms used to render structural damage and gridded overpressure and dynamic pressure contours including 2D contour planes, 3D isosurfaces, and volume rendering, have been upgraded to include rich RGB color schemes. In addition, full color map transparency now provides highly detailed visual access to view underlying model features. User defined color schemes are much more vibrant and the transition between colors is much smoother.

Exporting and Capturing Images - The exporting capabilities of ExDAM-V8.0 have been greatly expanded, providing a full suite of common graphical image and formats (including .gif, .jpg, .tif, .png, and .bmp) with options for increasing image resolution and controlling image quality of graphics image files. These high-resolution images can either be exported to a separate graphics file for manipulation with third-party editing software or inserted directly into a report document.

Printing Options - Previous versions of ExDAM-V8.0 offered limited options for customizing the print layout. ExDAM-VIII now includes a more flexible page layout for adding image descriptions, project descriptions, and other informative information.

The High Explosive Damage Assessment Model (HEXDAM) is designed to evaluate the damage caused to structures within a facility as a result of a primary explosion and any accompanying secondary explosions.

The application can also predict injury to an unlimited number of personnel in the facility. The principal use of HEXDAM software is for site analysis of explosive storage and manufacturing facilities; however, the software can also be used to evaluate terrorism and sabotage threats to an industrial or military facility.

VExDAM

BREEZE VExDAM can be used as a damage / injury assessment tool to determine the amount of blast damage / injury done to individual structures / persons in a certain geographical area due to a vapor cloud explosion.

This type of information would be helpful in determining the potential for destruction / injury at an industrial facility where significant amounts of combustible hydrocarbons are manufactured, handled, and / or stored. Such information should also be useful in evaluating the risk represented by acts of terrorism or sabotage to such an industrial complex. Other information may be useful in determining whether structures subject to explosion (storage tanks, fuel stockpiles, etc.) received enough damage to explode, and if so, how much additional damage / injury was done to other structures/ persons in the vicinity of the explosion.

Because of the shielding algorithm in BREEZE VExDAM, the effects of the presence of a shielding wall or a blast deflector can be taken into account.

VASDIP

According to current single-degree of freedom models, blast damage / injury can be communicated with pressure-impulse (P-I) diagrams. VASDIP uses the most recently developed P-I diagrams and allows users to specify detailed properties (including boundary conditions) of 24 different basic structural components and 19 different human body components.

VASDIP is an excellent companion product to BREEZE HExDAM / VExDAM, as it computes the corresponding vulnerability parameters for use within these applications. In addition, users have the capability to compute changes in vulnerability as a function of individual structural / human properties. This functionality makes VASDIP invaluable in cost / risk assessment and analysis.

BREEZE VASDIP capabilities include:

• Capacity to handle both inanimate structures and human body components
• Generate P-I diagrams
• Calculation of damage / injury for a given pressure and impulse
• Calculation of vulnerability parameters for use with BREEZE HExDAM and VExDAM

BREEZE VASDIP generates three distinct outputs. The first is a color-coded P-I diagram that provides the user with a clear picture of the three zones of structural / human response:

• Total destruction / fatality zone
• Partial damage / injury zone
• No damage / injury zone

The second output consists of specific vulnerability parameters used for characterizing a structure / human body with HExDAM and VExDAM software. The third output consists of damage / injury level resulting from a given pressure and impulse.

BREEZE VASDIP calculates explosive safety and physical security parameters for use in predicting possible damage to buildings and humans resulting from an external explosion.

The parameters that can be accounted for with VASDIP vary with each structural/human component and are quite comprehensive. For example, for a reinforced concrete slab, the following parameters can be specified:

• Slab span 
• Cross-sectional area 
• Section width
• Tensile steel area
• Boundary conditions
• Yield strength of reinforcement 
• Compressive strength of concrete 
• Depth of tensile reinforcement 
• Weight density of section

For human body components, the following parameters can be specified:

• Body weight
• Body height
• Height-to-width ratio
