MODELLING & ENGINEERING


Partnership on 3D imaging and analysis


VSG, Visualization Sciences Group, and Xradi have signed an OEM partnership agreement. Xradia will offer VSG’s Avizo Fire software for 3D visualisation and analysis used in conjunction with its 3D X-ray imaging solutions.


The offering enables fast analysis and modelling of Xradia’s 3D imaging solutions for computed tomography at true submicron and nanometer levels of resolution, combining the best in-class solutions by both companies. This combination enables and facilitates a wide range of research, engineering and industrial applications. For example, in the oil and gas industry, X-ray CT-derived 3D segmented pore structures of rocks are used as the


base grid systems for applying digital rock physics modelling of static and dynamic rock properties including porosities, permeabilities, multi-phase relative permeabilities and capillary pressures. These properties are essential for resource assessment and for production design and optimisation of oil and gas assets. ● In a separate development, Visualization Sciences Group (VSG) has acquired Noesis, a leader in image processing and analysis software, and has also signed a global partnership agreement with Schlumberger, expanding the integration of VSG’s Open Inventor technology across the whole range of Schlumberger software products.


ELECTRICAL DRIVE SYSTEMS AIDED BY MODELLING AND SIMULATION


Thien eDrives, a developer of electrical drive systems, is using Matlab and Simulink, from MathWorks, to model, simulate and implement an electric motor control system on TI’s C2000 microcontroller unit (MCU). By applying Model- Based Design, Thien eDrives moved rapidly from the fi rst prototype to the fi nal series, reducing development time by 50 per cent. To develop an electric drive for a fuel cell vehicle compressor unit, including the motor control software, electronics, motor, and other mechanical components, Thien eDrives needed a design


Electromagnetic design software aids superconducting magnet systems


Advanced electromagnetic simulation software is helping a leading producer of cryogenic equipment to speed the development of application-specifi c superconducting magnets for research. The software – the Opera 3D simulator – has been provided by Cobham Technical Services to Cryogenic. The package includes a suite of 3D electromagnetic design, simulation and analysis tools, plus a unique optimiser. This latter tool automatically employs multiple goal-seeking algorithms


to eliminate the need for manual intervention when evaluating the best solution for a particular design. Cryogenic designs and manufactures a wide range of superconducting magnets and associated measurement systems for laboratory research and industrial uses worldwide. Generally, Cryogenic uses its own in-house software to design the basic mechanical layout and coil structures of a magnet, fi ne tuning its fi eld profi le with magnetic material to meet


the customer’s specifi c needs. The shape and placement of the magnetic pieces are critical to the magnet’s performance, and are determined through extensive electromagnetic fi eld simulation. Following the initial design phase, the company employs Opera’s 3D Modeller to create a very detailed geometric model of the proposed design, from which is generated a mesh of fi nite elements for numerical solution using the static electromagnetic fi eld simulator.


Faraday Technology uses Model-Based Design from MathWorks


Faraday Technology, a fabless ASIC and SIP provider, is using MathWorks’ Model-Based Design to accelerate the development of SoCs, including development of its NAND Flash Controller error correcting code (ECC) engine. Matlab and Simulink products have helped Faraday accelerate development of more effi cient designs by completing system-level simulations

200 times faster, increasing throughput by 15 per cent, and cutting gate count by up to 57 per cent. Faraday is positioned to capitalise on new business opportunities as more integrated circuit manufacturers seek advanced SoC designs. To meet this demand, Faraday established a faster and more cost-effi cient workfl ow to develop memory controllers for


microprocessor subsystems. Faraday adopted Model-Based Design to accelerate SIP development, explore system-level design alternatives, and improve communication among engineers. This approach has helped reduce gate count, shorten the development cycle for memory controllers and other modules, and differentiate itself through lower cost.


approach that enabled early verifi cation of control strategies, code generation, and rapid design iterations throughout the project. Model-Based Design allowed for verifi cation at multiple stages of development, helping produce a high-quality component within a shortened timeframe. Automatic code generation eliminated the time-consuming and error-prone hand-coding process while providing added confi dence of compliance with certain MISRA C standards. Using models also simplifi ed design reviews with Thien eDrives customers by eliminating the need for code review-driven processes.


IN BRIEF


LMS International has acquired a 60 per cent controlling majority stake in Samtech. LMS Samtech will be the home of the worldwide aerospace simulation business within the LMS Group. Romanian electric power grid company, Transelectrica, is using @RISK from Palisade to enable it to operate as a commercial organisation as the country’s power industry opens up to competition. GEA Niro has been working with the Technical University of Denmark (DTU) to simulate the fl uid dynamics that take place within a full-sized spray dryer.
