Newsletter for April 2010

Webinar with the IEEE & NI

Recording now available!

Thank you to everyone who attended our webinar with the IEEE & National Instruments on March 25th. A recording is now available here.

This seminar features experts from two of the leading engineering modeling and real-time simulation tool providers. They present an overview of modeling and simulation of complex engineering systems using physical modeling techniques that are derived from symbolic model formulation techniques. They show the advantages these techniques provide for implementations in real-time simulation systems for HIL testing.

To illustrate this process, applications are presented that begin with multi-domain system model development in MapleSim, and then are deployed to a range of real-time simulation platforms from National Instruments. Examples feature the new real-time testing software, NI VeriStand™, a ready-to-use software environment for configuring real-time testing applications, including hardware-in-the-loop (HIL) test systems.

Featuring Paul Goossens, Director of Applications Engineering at Maplesoft, and Chris Washington, Senior Product Manager - Real-Time Testing & HIL Simulation, National Instruments.

Maplesoft Opens Office in Germany

Maplesoft is happy to announce the opening of its first office in Germany. The move to localized sales and support in Germany underscores the importance of the German and Austrian market for Maplesoft. With the opening of this office, Scientific Computers will no longer act as Maplesoft’s reseller in Germany and Austria. Maplesoft is working closely with Scientific Computers to ensure a smooth transition for existing users.

The Maplesoft office in Germany is now open, and local representatives are available to support all new and existing customers. To contact the Maplesoft office in Germany, please call 49-241-980919-30 or email germany@maplesoft.com. Some members of Scientific Computers’ staff have become Maplesoft employees, so that customer relationships – both business and technical – will not be interrupted

MapleSim used in the develoment of a wind turbine system

Wind power generation represents one of the many important new green technologies that are being developed to address climate change in the 21st century. Learn how a customer in the energy sector uses MapleSim in a crucial phase of the development of a wind turbine power generation system.

Wind Turbine SystemThe challenge:
The customer needs to develop a predictive model of a wind turbine. The model will be used to develop control strategies that will maintain a steady, predictable power output despite the highly variable and unpredictable changes in wind conditions. The system needs to adapt quickly to changes in wind speed and direction by changing the direction of the nacelle (the pod that contains the power generation components) and the angle of attack of the propeller blades with respect to the wind direction and speed.

The solution:
A multi-domain model that incorporates mechanical, signal blocks, controllers, and electrical components was created in MapleSim. The mechanical portions include the generator tower, propeller, and nacelle. A positional controller on the nacelle was created to respond to previously measured wind speed/direction data provided in an Excel® spreadsheet. When a simulation was performed with varying wind conditions, it showed that the blade angle changed in response to changes in wind speed and direction, resulting in a relatively constant blade speed producing a near-constant power output of 300KW, as desired. Because the wind turbine model is fully parameterized, it can be easily updated for different configurations and operating conditions.

The Challenge of the Challenger Puzzle
Dr. Robert Lopez
I have always wondered about this puzzle - there are twelve numbers to be determined by some ten equations, and the condition that the numbers are integers between one and nine. To what extent will these conditions determine the solution to the puzzle?

Using Sliders to Vary Parameters in an Initial Value Problem
Dr. Robert Lopez
The physics instructor who asked how to build such a tool had both solutions in his hands before the end of the day on which I received the question. It was a Friday afternoon, and when I got back on Monday morning, I found "words cannot say..." in my inbox, sent over the weekend, from Greece from whence the question came.

Application Center Highlights
Application
Electronic Wedge Brake
Author: Maplesoft

A 12V DC motor is connected to a worm gear that pushed on the side of a wedge. The force and displacement of the wedge are directed 90-degrees towards the brake pad surface. The slope of the wedge determines the force and displacement ratio.

Scientific software goes parallel
Desktop Engineering , March 31, 2010

Extract: “’Our goal for the future is to keep expanding the set of operations where multi-processing happens automatically and without further user intervention, while always allowing an expert user to override the defaults and interact with Maple's parallel toolkits at a low level in order to achieve the best possible performance,’ said Laurent Bernardin, executive vice president of research and development at Maplesoft.”
