This software is developed to comply to Automotive SPICE® and Functional Safety ISO 26262 standards.

# How Software Defined Radios solve challenges of Spectrum Monitoring and real time Direction Finding

As the variety and complexity of communication systems in the modern RF battlefield increase, the need to quickly design, deploy and field upgrade spectrum monitoring and direction finding solutions becomes paramount. Software Defined Radios (SDR) with user programmable FPGAs are uniquely positioned to be the platform that will keep pace with the rapidly changing ecosystem of algorithms and technologies.

# A Modern Electric Bus Fleet: Improving Public Transit with System-Level Modeling

### In Conjunction with SAE

As cities across the world continue to increase in both population and density, public transportation plays a critical role in creating liveable cities. The current adoption of electrified transportation, however, presents a wide array of new challenges that must be carefully considered before these systems are implemented.

# Product of the Month: October 2017

ANSYS, Canonsburg, PA, introduced ANSYS® Discovery Live™ simulation software that allows engineers to immediately examine the impact of their design changes. Users can pose what-if questions upfront in the design process to rapidly explore thousands of design options and receive immediate feedback. The software supports fluids, structural, and thermal simulation applications, enabling engineers to experiment with design ideas and see instant feedback. Users can run an analysis-first approach as they design, allowing them to iterate with a 3D model, and interactively explore the impact of simple and complex changes. The environment provides users with instant simulation results, tightly coupled with direct geometry modeling. The simulation technology is based on the parallel nature of NVIDIA graphics processing units (GPUs).

# MSET Industrial Early Warning System

### MSET is applicable to any industry in which continuous operation and safety are imperative, including the power industry, manufacturing, aerospace, and pharmaceuticals.

System breakdowns in modern industrial environments can result in millions of dollars in lost time and productivity, and even the loss of life and property. In the utilities industry — where the continuous operation of coolant pumps is essential — the breakdown of a single pump can result in a loss of as much as $10 million in downtime.

# Robust Mesh Update Method for Grid Motion Problems

Over the past several decades, one class of problems in computational fluid dynamics (CFD) that has undergone substantial development involves movement of the fluid domain boundary. The problem class exists when the fluid domain boundary is either explicitly time-dependent, or is known a priori and determined as part of a flow solution in a coupled fashion. Free-surface fluid-structure interaction and forced-motion flows are typical of problems in this class. More specifically, as a boundary moves, a CFD mesh simulating the fluid dynamics can experience mesh cell distortion to the point of cell collapse, thereby rendering the CFD mesh meaningless.

# An Upwind Parabolized Navier-Stokes Solver (UPS) for Supersonic and Hypersonic Flow Simulation, Version 6.1

The simulation of high-speed flow involves unique challenges such as the treatment of strong flow gradients associated with shock waves and expansion fans, as well as the modeling, at hypersonic speeds, of air chemistry effects. However, supersonic flow also produces the effect of limited zones of influence, which allows for single-sweep flow solution processes. The parabolized Navier-Stokes (PNS) equations are a modification of the equations of fluid flow that extend this inherently supersonic property into the subsonic portion of the boundary layer in viscous flows. Solution methods for systems that are hyperbolic/parabolic in a spatial direction can be obtained using a space-marching approach that can be an order of magnitude faster than using a time-marching method on the time-dependent Navier-Stokes equations.

# Efficient Two-Dimensional Solution Methods for the Navier-Stokes Equations

ARC2D is a computational fluid dynamics (CFD) program for two-dimensional airfoil and simply connected geometries. The program uses implicit finite-difference techniques to solve two-dimensional Euler equations and Navier-Stokes equations. It is based on the Beam and Warning implicit approximate factorization algorithm in generalized coordinates, in a variety of block or diagonal forms. The methods are either time-accurate (e.g., dual-time-stepping or Runge-Kutta methods) or accelerated non-time-accurate steady-state schemes. The evolution of the solution through time is physically realistic; good solution accuracy is dependent on mesh spacing and boundary conditions.

# Using SysML to Model Layered System Interfaces

To produce accurate system architecture descriptions, it is essential to be able to describe interfaces between system elements at different levels of abstraction and from different perspectives at the same time. For example, the connection from system A to system B may be viewed at a high level as independent of the mechanisms that implement that flow (copper wire, free space RF, optical), and it may be useful to explore which of several of these mechanisms might be used. It is also frequently useful to analyze and constrain the problem (interface bindings) at several levels of detail (application protocols, network protocols, physical layer connections) separately, as well as in combination.
