SOUTHWEST RESEARCH INSTITUTE
Modeling and Simulation Overview
Modeling and simulation is a discipline that is used to develop an understanding of the interaction of the parts within a system. This acquired level of understanding leads to a better understanding of the system as a whole. Southwest Research Institute (SwRI) has been using modeling and simulation to solve complex science and engineering problems for more than 50 years.
Because more and more emphasis is being placed on reduction of time and money spent on product development, modeling and simulation continues to be an effective way to verify, validate, calibrate and achieve results without the need for procuring prototype parts, other expensive components. SwRI is prepared to analyze the client's needs, design solutions, and develop strategies, methods, models and media to provide effective and affordable solutions. Some of the areas in which SwRI offers modeling and simulation are discussed below.
Avionics and Support Systems Modeling and Simulation
In today’s world, simulation models are essential in enhancing scientific understanding through the use of system development, management, and planning. SwRI has applied modeling and simulation solutions in support of technologies that include aircraft avionics, ballistics, and unmanned systems.
SwRI’s efforts to develop efficient simulation models are important in reducing non-recurring engineering cost through:
SwRI engineering staff applies Model Based Design techniques to develop ballistic models, design weapon scoring algorithms, and test real-time software. SwRI staff evaluates fire control avionics with a mission replay tool which includes a hardware-in-the-loop (HIL) simulation. Previous efforts included redesign of avionics hardware.
Modeling and simulation technologies are also applied to evaluate developed algorithms using kinematic and dynamic models of unmanned systems. This provides the capability to experiment and analyze the real world effects while eliminating physical, environmental, and economic restrictions. The developed environments provide the investigation of manned and unmanned systems interaction ranging from performance-limiting factors to integrated technologies.
The elements of the modeling and simulation capabilities that span many applications across air and land systems include developing:
In developing state-of-the-art technology capabilities, lab facilities include:
ISO 9001:2000 Registered and AS9100 Compliant

Geologic Modeling and Simulation
SwRI's Geosciences and Engineering Division has developed effective approaches to building and analyzing geomechanical models of complex geologic structures, including:
When coupled with realistic rock properties, geomechanical simulation provides a valid forward model that can be used to validate a geometric and kinematic restoration.
SwRI has developed a new technique to produce digital terrain models (DTMs) of the deformed model upper surface using dynamic structured light (DSL). Using this technology, scientists quantify the morphology of deforming models in high resolution and expand the data derived from laboratory simulations of geologic deformation.
Physical analog modeling is a well-established laboratory technique for reproducing the developmental sequence and overall geometry of geologic structures. SwRI's Physical Modeling Laboratory is a state-of-the-art facility designed to emulate a variety of tectonic settings. The modeling apparatus is modular and can be configured to represent most tectonic deformation styles, including:

Modeling and Simulation of Network and Radio Communications and Security
The Applied Sensing Department at SwRI is an interdisciplinary department with broad experience in modeling and simulating complex systems. We have applied our expertise in communications modeling and simulation to:
Effective modeling and simulation of today’s complex communications systems requires a team of scientists and engineers with experience in a broad range of capabilities such as Internet and wireless network protocols and standards, radio frequency (RF) engineering, computer science, hybrid and ad hoc network design, and cyber security. Our staff of engineers and scientists has expertise in:
In addition to a qualified staff, high-end tools and equipment are required that facilitate realistic traffic generation, that are able to operate at the speed of today’s communications backbones, and that enable hybrid simulations which meld simulated communications elements with actual hardware. SwRI’s Network Simulation and Test Laboratory is equipped with state-of-the-art hardware and software such as:

Radar and Electronic Warfare Modeling, Simulation, and Analysis
SwRI has broad experience in the modeling, simulation, and analysis of radio frequency (RF) systems, antennas, radars, and electronic warfare systems. In the context of today’s tool-rich environment, we have the experience to integrate these best-of-class tools to leverage the combined core strengths of the tools to meet the objectives of the modeling and analysis effort. SwRI engineers have experience integrating tools such as Satellite Toolkit (STK) and MATLAB® to combine advanced algorithm development, orbit simulations, and data visualization.
SwRI engineers have evaluated, developed, deployed, and verified computer-based threat analysis systems for more than a
decade. Our staff has extensive experience in the design, development, deployment, testing, and maintenance of systems used by military organizations to evaluate data collected by a number of sources, analyze planned courses of action, and reduce the development time and cost for complex systems.
SwRI has conducted research in the design of novel antenna topologies and simulation of single and multi-antenna systems. In addition to having optimized design parameters for given antenna topologies for specific applications, entire platform simulations have been conducted to determine the optimal placement of a set of antennas with regard to co-site interference and calibration challenges. Simulations can also include monte-carlo and worst-case simulations to extrapolate the effects of changes in element performance to entire phased array systems.

SwRI has experience with the following methods:
SwRI engineers design and develop modeling and simulation systems that are used as test environments for factory control systems development. This allows for performance testing of software against a complete scale model of the plant floor without requiring downtime of the systems as is typical in system software testing in manufacturing. SwRI builds test frameworks that model each individual aspect of the manufacturing process, including:
These individual models are combined into a plant model and developed software code is “plugged in.” This realistic modeling allows simulations to be run that show the impact the developed software algorithms will have on the manufacturing process.
SwRI’s ability to validate manufacturing software design and development through simulation provides a low-cost solution to verifying the performance characteristics of the system prior to deployment without the burden of shutting down the manufacturing environment and reconfiguring software systems to allow for software testing.
