About us
Simulations provides scientific and engineering services supporting defense and commercial research and development, rapid prototyping, and full-service engineering. We design and build things. We ask questions. We listen. We get the details—and then we build it. Our work is driven by new technology programs, mission-critical requirements, and the need to develop capable systems from first principles through delivered hardware.
We are a materials development and engineering firm working across multiple material systems, with a core specialty in advanced composite materials. Our team integrates materials science, structural engineering, and manufacturing to produce reliable, defensible solutions for demanding operational environments. We are analysts, designers, engineers, manufacturers, and program managers—experienced practitioners who back every design with analysis, data, and proven engineering judgment.
Our work is grounded in first-principles engineering and a disciplined understanding of governing physics. We believe that credible engineering requires traceable reasoning, defensible assumptions, and the ability to connect analytical predictions with real-world hardware performance. This approach allows us to support advanced technology programs where reliable answers must often be developed in environments with limited precedent or incomplete information.
Simulations supports defense and government-sponsored programs where performance, reliability, and schedule matter. Our designs are validated through numerical simulations, closed-form solutions, established design practices, empirical testing, and governing physical principles. Our analysts are proficient in implicit, explicit, nonlinear, dynamic, and transient finite-element modeling, grounded in classical engineering and mathematical foundations.
Our experience includes the design and engineering of mechanical and electromechanical systems, high-energy propulsion structures, gun-launched projectiles, missile components, systems, military hardware, specialized tooling, diagnostics, and mission-specific equipment. From early literature research through delivered hardware, we support system coordination, subsystem engineering and analysis, conceptual and industrial design, three-dimensional modeling, drafting, prototyping, production hardware, technical documentation, consulting, and software development.
A defining characteristic of Simulations is disciplined, cost-effective execution.

SKILLS & MARKETS
Materials & Composites
Simulations is a materials development and composite engineering company with broad, hands-on capability that extends well beyond structural design. We engineer composite systems from the material level upward—developing architectures, processing methods, tooling, and validation strategies that enable performance in extreme mechanical, thermal, and dynamic environments. Our work and our technologists skills span the defense and industrial sectors, and novel structural applications where material behavior defines system success.
We work across a wide range of fiber and matrix systems, including boron, carbon, glass, Kevlar, and advanced polymer matrices such as BMI, cyanate esters, polyimides, and an extensive spectrum of epoxies. Our composite solutions include prepreg systems, custom resin formulations, and custom-designed weaves and braided architectures tailored to specific load paths, strain-rate environments, and manufacturability constraints.
A core differentiator is our ability to validate material performance in-house. Simulations performs extensive composite and material testing using a 66-ton Shimadzu universal testing machine, enabling precision compression, tensile, bending, and failure characterization. This tight coupling between materials development, fabrication, and testing allows rapid iteration and defensible performance claims.
Our composite manufacturing capability includes the design and fabrication of custom molds, inflatable and expandable bladder systems, trapped rubber molding, soluble mandrels, and specialized tooling required for complex internal geometries and high-quality consolidation. These processes support applications ranging from lightweight composite sabots and gun-launched interceptor structures to missile and projectile airframes and large-scale composite tubes exceeding 44 feet in horizontal span.
Simulations is recognized for state-of-the-art high-compressive-strength composite systems, including boron-based architectures demonstrated at 588 ksi compressive strength, enabling applications where conventional composites fail—such as gun-launched, high-acceleration interceptors and rocket systems.

Lean and Highly Cost-Effective
Our lean structure allows us to deliver the analytical depth and rigor typically associated with much larger engineering organizations, while maintaining cost efficiency, schedule responsiveness, and technical accountability. Modeling and simulation at Simulations is focused on supporting acquisition decisions, not generating academic reports.
Modeling and simulation are foundational to how Simulation engineers materials, structures, and systems. Our analysts apply governing physics, classical mechanics, and advanced numerical methods to deliver decision-quality analysis supporting design, materials selection, risk reduction, and system qualification. We routinely operate in regimes where linear assumptions fail and nonlinear, transient, and coupled physics dominate performance.
Simulations employs the full spectrum of finite element analysis (FEA), computational fluid dynamics (CFD), and multi-physics modeling to support defense and industrial programs. Our work spans implicit and explicit formulations, high strain-rate and shock-dominated events, extreme thermal environments, and high-speed aerodynamic and aerothermal regimes, including Mach 6+ modeling.
All modeling activities are tightly coupled with fabrication realities and empirical validation. Simulation results are used directly to guide material architecture, structural configuration, tooling decisions, and test planning—ensuring analyses are not only accurate, but actionable.
Simulations provides independent, in-house modeling and simulation capability that reduces technical risk, shortens development cycles, and minimizes reliance on external analysis vendors. Our analyses are performed by senior, career engineers and are directly tied to hardware design, fabrication, and testing—enabling faster transitions from concept to validated capability.
Finite Element Analysis (FEA)
Simulations routinely performs all major classes of FEA required for advanced engineering programs, selecting solution methods appropriate to the governing physics, loading regime, and material behavior:
- Linear static analysis for elastic response, stress distribution, deformation, and margin assessment
- Nonlinear analysis addressing plasticity, large deformation, damage progression, and evolving contact
- Modal analysis for natural frequencies and mode shapes, supporting vibration and resonance control
- Dynamic and transient analysis for impact, shock, blast, gun-launch, and high-acceleration environments
- Thermal and thermomechanical analysis for heat transfer, gradients, and thermally induced stress
- Fatigue and durability analysis for cyclic loading and life prediction
These methods are applied across composite, metallic, ceramic, and hybrid systems.
Advanced & Specialized Numerical Methods
For systems operating near material or structural limits, Simulations applies advanced numerical techniques to resolve behavior that conventional methods cannot capture reliably.
- Ceramic crack initiation, growth, and failure prediction, including probabilistic approaches
- Extended Finite Element Methods (XFEM) for discontinuities and fracture without remeshing
- High-order and adaptive finite element methods for stress concentrations and wave propagation
- Shock- and wave-dominated response modeling relevant to ballistic and launch environments
These tools are routinely applied where failure modes must be predicted with confidence—not inferred.
Computational Fluid Dynamics & High-Speed Flow
Simulations performs CFD and coupled aero-structural analysis across subsonic, supersonic, and hypersonic regimes. Our analysts support aerodynamic and aerothermal modeling for vehicles and components exposed to extreme pressure, temperature, and heat-flux environments.
- External and internal flow analysis
- Aerodynamic and aerothermal simulations
- Mach 6+ high-speed flow modeling
- Coupled thermal–structural response
These analyses directly inform material selection, structural sizing, and survivability assessments.
High-Performance Computing & Toolsets
Simulations maintains in-house high-performance computing resources to support large-scale nonlinear and transient analyses:
- Multi-core compute servers with GPU acceleration
- Commercial-grade engineering solvers and preprocessors
- Secure, controlled analysis environments
This infrastructure enables rapid iteration, parametric studies, and sensitivity analyses critical to early-stage development and risk reduction.
Commercial
Simulations applies defense-grade engineering rigor and materials expertise to commercial and industrial systems where performance, durability, manufacturability, and cost discipline must coexist. We work with customers at every stage of development—from concepts sketched on paper to prototypes requiring industrialization and full-scale production. Our teams routinely take designs from scratch and bring them to reality, or transform early prototypes into reliable, manufacturable products.
A hallmark of our commercial work is large-scale composite structural design. Simulations pioneered the design, engineering, and manufacturing of composite tubes for the leading-edge pool cover industry, developing systems capable of spanning over 44 feet horizontally while maintaining stiffness, durability, a positive crown (no droop), and repeatable manufacturability. This work required advanced composite architecture development, structural finite element analysis, custom tooling, and tightly controlled fabrication processes—capabilities that readily transfer to other long-span and load-critical commercial applications.
We routinely perform structural analysis using finite element methods across a wide range of commercial platforms, including boats and marine transportation systems, heavy-load trailers, and specialty structures. Our experience spans both static and dynamic loading, environmental durability, and long-term service considerations, allowing us to support both design optimization and certification-driven analysis.
Simulations also supports medical and life-safety products, including IV catheter design and analysis, commercial chemical mixing machines used in catheter component production, and patient assistive devices. These programs demand careful balance between mechanical performance, manufacturability, regulatory considerations, and cost—an area where our integrated design-analysis-manufacturing approach provides clear advantage.
Beyond traditional mechanical systems, Simulations has developed smart, wireless alarm systems for firefighters, designed to alert operators when hoses disengage from fire trucks, improving safety and situational awareness. Additional commercial systems include aquatic exercise equipment and rotary engine design, demonstrating the breadth of our engineering and product development capability.
What differentiates Simulations in the commercial space is how we work. We are a low-overhead, execution-focused engineering and manufacturing company. We do not require layers of management, endless meetings, polished slide decks, or continuous video conferences to make progress. Decisions are made by senior engineers at the bench, backed by in-house analysis, testing, and manufacturing capability. We are the company that picks up the tool, turns the screwdriver, and builds, with a full analytical team standing behind every decision.
For commercial customers, this translates to faster development, lower cost, and direct accountability—without sacrificing engineering discipline or product quality.
