Condensation in automotive head lights can be detrimental to consumer acceptance of a product and in certain instances lead to recalls and warranty issues. This presentation describes a numerical method for transient simulation of liquid film formation process on the surface of an element in a head light as part of a CFD thermal analysis.
Automotive LED headlight reliability and optical performance requires careful thermal design especially due to LED operating temperature & radiometric performance. As part of this condensation simulation topic, adequate radiative heat transfer modeling is described on using a “band” Monte-Carlo radiation model. This enables proper simulation of the focusing influences of semi-transparent materials (glass, plastic), reflective and refractive surfaces in a complex headlight design.

Mentor Graphics Corporation (NASDAQ: MENT) announced the newest version of the Flowmaster® 1D computational fluid dynamics (CFD) software product for fast and accurate thermo-fluid systems design. The new Flowmaster solution features several key new and enhanced functionalities including an improved multi-arm tank component, and integration with complementary 1D pipe stress products such as CAESAR II and CAEPIPE for pipe fluid-force predictions. Overall product enhancements to usability and increases in physical modeling capabilities provide unparalleled accuracy and ease-of-use to the automotive, aerospace, power generation and gas turbine markets.
The enhanced usability and physical modeling capabilities in version 7.9.4 of the Flowmaster product include:
FLEXConnect.IVI Improves IVI User Experience and
FLEXConnect.ANC Reduces In-Vehicle Noise
Mitsubishi Electric announced two new FLEXConnect™ In-Vehicle Infotainment (IVI) systems. FLEXConnect.IVI provides a three-screen user interface that is both intuitive and cost effective, and FLEXConnect.ANC is an Active Noise Control (ANC) system that cancels less predictable and harmonically unrelated road sounds.
The FLEXConnect architecture is a family of systems that extend typical infotainment uses by allowing easy access across multiple devices over Ethernet and Wi-Fi. Last year Mitsubishi Electric introduced the FLEXConnect series with FLEXConnect.RSE, (Rear Seat Entertainment). FLEXConnect.RSE features two rear-seat screens that allow the user to stream multiple contents per individual preferences while operating as independent units controlled through the Ethernet AVB architecture.
Mentor Graphics (NASDAQ: MENT) announced the availability of Automotive Ethernet support in the Volcano™ VSA™ product for network design of both AUTOSAR-based and non-AUTOSAR electronic control units (ECUs).
Increasingly, in areas in which high bandwidth and reliable performance are essential, Ethernet is being used. These include advanced driver assistance systems (ADAS), vehicle network backbones, audio video bridging (AVB) systems, and diagnostic communication over Internet Protocol (DoIP).
The Mentor® Volcano VSA tool addresses the network-wide timing analysis challenges where a mixture of CAN, FlexRay, and Ethernet-based network busses co-exist. The AUTOSAR standard supports timing definition for all elements in a mixed-topology network. The Volcano VSA tool addresses the challenge of accounting for the many different timing paths.
Mentor Graphics Corporation (NASDAQ: MENT) announced several new capabilities including a new Functional Mock-up Interface (FMI) and enhancements to secondary air analysis for its Flowmaster® simulation software solution for thermo-fluid systems.
The Flowmaster product is used at every stage of development, from concept through design optimization and validation, providing minimized design effort to accurately simulate complex systems. The latest release contains new functionality addressing the needs of the automotive and other industries.
The new FMI enables usage of Flowmaster models in an open-source environment, thereby allowing systems engineers to use models created by different simulation tools in a true collaborative environment.
Mentor Graphics Corporation announced the newest version of its Mentor(®) Embedded Hypervisor product offering advanced features for system configuration, debugging, and hardware support for developing robust, reliable, and secure applications.
This solution enables high-performance applications for industrial, medical, automotive, networking, telecommunications and consumer electronics products.
The new Mentor Embedded Hypervisor product provides data-driven configuration and device trees for guest resource partitioning instead of hard-coded guest resource tables contained in each board support package. This enables easier system build and configuration.
Mentor Graphics Corporation announced a new version of the Mentor® Embedded Nucleus® real time operating system (RTOS) targeting high-performance, next-generation applications for connected embedded devices.
The Nucleus RTOS process model is expanded to include ARM® Cortex® M- based cores. For the first time, software developers can use a single embedded operating system to increase system reliability through memory partitioning for the entire spectrum of ARM cores, facilitating code reuse across an entire product family comprising low-end to high-end devices.
New in this release is a multicore framework to manage inter-process communication (IPC) and processor life cycle for complex heterogeneous system-on-chip (SoC) and enhanced Nucleus RTOS graphics capabilities with Imagination and Vivante GPU support.
Anne Cirkel of Mentor Graphics to serve as General Chair
The Design Automation Conference (DAC), the premier conference devoted to electronic design and design automation, has named the members of the 52nd DAC Executive Committee. The Executive Committee (EC) oversees the exhibition and trade show, plans the technical program, establishes new initiatives, and manages conference operations and publicity.
The 52nd DAC will be held at the Moscone Convention Center in San Francisco, CA, from June 7-11, 2015.
At the EV Roadmap 7 Conference in Portland, officials from the U.S. Department of Energy (DOE), Drive Oregon, Intel, Portland General Electric (PGE), the State of Oregon, and other regional businesses announced their participation in DOE’s Workplace Charging Challenge – a collaborative effort to increase the number of U.S. employers providing access to electric vehicle charging stations for employees.
With 76 stations across 11 campuses in the U.S., Intel Corporation is one of the five largest providers of workplace charging in the Energy Department initiative. Marty Sedler, Intel’s Director of Global Utilities and Infrastructure, said, “As a leading technology company, Intel is pleased to help our employees make sustainable transportation choices, and we hope our example will inspire others.”
Mentor Graphics Corporation announced what it described as the embedded software industry’s first comprehensive solution for heterogeneous multicore system-on-chip (SoC) development.
Heterogeneous architectures are those which combine two or more different types of microprocessors or microcontrollers. They enable the development of advanced embedded systems that consolidate functionality and connectivity to produce high-performance embedded devices.
Mentor Graphics is delivering an integrated development solution that spans device configuration, deployment and system optimization for multi-operation system devices that include the Linux® platform, real-time operating system (RTOS), and bare-metal applications. This solution helps design teams to quickly develop high-performance applications for industrial, medical, automotive, telecommunications, networking, and consumer electronics products.
