IMPETUS Defense: Leading Simulation for Aerospace & Defense
Impetus Defense is a software modeling system that provides accurate, 3D simulations of the extreme physics of combat ballistics. Used by vehicle and armor manufacturers, munitions, missile, and drone designers, and structural engineers, Impetus offers a full suite of GPU-accelerated analytical tools for a wide range of modeling applications and simulation methods.
Impetus Defense provides four physics-based, computational engines including Finite Element Analysis, Discrete Particle Dynamics, Smoothed Particle Hydrodynamics, Computational Fluid Dynamics, two additional toolsVulnerable Area Assessments, Vulnerability/Lethality, and a comprehensive library of digital twins with inert and energetic materials, munitions and other objects to speed up analysiss.
Impetus is ISO 27001 certified, and the software is available for on-premises and deployments desktop workstations and large networks including GPU clusters . Licensing is managed by entity and projects, not by the user, so organizations and engineering teams can work collaboratively and effectively.
Modeling Drone Attacks
FPV drones have changed the game in modern warfare. With Impetus, armored vehicle manufacturers and field adaptation engineers are now able to simulate drone-carried shaped charge and high-explosive attacks with accuracies previously available only at national laboratories and major prime contractors. For both UAS and counter-UAS design and simulations, Impetus Defense can reduce the significant financial costs and challenges of physical testing and evaluation.
Shaped Charges & Target Interactions
Impetus Defense provides processor-efficient simulations by combining Smooth Particle Hydrodynamics for shaped charge munition liners and casings along with Finite Elements or Computational Fluid Dynamics to simulate explosive materials. Shaped charge jet length, shape, and velocity profiles and particulation data are output automatically, and effects are rendered visually in Impetus' smart user interface. Impetus Defense includes built-in templates for common shaped charges and explosively-formed penetrators.
Fragmentation Modeling
Impetus specializes in fragmentation modeling with advanced finite element analysis tools. Impetus Defense calculates high-order finite elements for large deformations, provides stochastic distributions of initial damage from varied fragments, and node-splitting algorithms to prevent material loss in simulated fractures. Impetus ensures accurate, physics-based simulations of explosive and reactive fragmentation processes that are crucial for modeling in defense and civilian engineering.
Blasts & Structural Interactions
Impetus Defense's GPU-accelerated, ultra-fast Computational Fluid Dynamics tool is ideally suited for air-blast simulations, particularly contact detonations and urban blast scenarios. Impetus also excels in calculating intricate fluid-structure interactions, such as mine blasts and effects on geometrically complex vehicle models. This combination enables deep insights and the ability to mitigate IED and other blast effects on a variety of stationary and mobile structures.
With Impetus Defense, engineers can import fragmentation distributions directly into the Impetus user interface for subsequent Vulnerability / Lethality Analysis tracking, along with air-draft effects, and interactions with user-defined targets.
