WALAIR++
High-Fidelity Blast Simulation From individual components to city-scale environments, WALAIR++ can simulate how blast waves propagate, interact with structures, and affect their surroundings. These examples demonstrate several of the platform’s analysis capabilities, including complex geometry, damage assessment, and breakable elements.
Blast Propagation in Urban Environments
Complex & Large-Scale Geometry
Visualize pressure-wave behavior and interactions across dense, complex geometries.
Rapidly model blast propagation through detailed buildings, infrastructure, and urban environments. The software can voxelize arbitrary STL geometry for use as rigid boundaries.
Damage Quantification
Human Injury Mitigation
Assess potential building damage using pressure-impulse criteria, with damage classifications automatically mapped onto surfaces.
Quantify potential blast effects on people, including eardrum rupture, lung damage, human velocity, and overall fatality risk, using criteria derived from experimental measurements.
See WALAIR++ in Action WALAIR++ is Thornton Tomasetti’s GPU-accelerated computational fluid dynamics software for high-fidelity blast analysis. Built for speed and scale, it enables complex geometries and large computational models to be processed and analyzed in a fraction of the time required by traditional CPU-based approaches, helping engineers explore blast effects, evaluate risk, and test design strategies more efficiently.
