MapleSim Connectivity Toolbox chosen as Editor's Pick of the Week

MapleSim™ Connectivity Toolbox has been selected by Desktop Engineering as the “Editor’s Pick of the Week.” Editor Tony Lockwood says, “Maplesoft, the engineering, science, and mathematics software developer that's been making the tools engineers have used to change the way the world operates for 20 years, is in on a tear. Back in January, I told you about MapleSim, their new multidomain tool that lets you diagram, simulate, and model complex systems that have real-world headaches like continuous and discrete signals, hydraulics, and analog, digital, and multiphase electric circuits. Today, it's the MapleSim Connectivity Toolbox, which lets you integrate your MapleSim models with Simulink®, the multidomain environment for designing and simulating dynamic and embedded systems from The MathWorks™. In two words: greater productivity.”

A Flight into the Future with MapleSim

Dr. Richard Gran is well placed to appreciate the benefits modern technology has brought to modeling and simulation. As a key member of the NASA team that designed the digital flight control system for the Apollo Lunar Module in the 1960s, he spent many months developing a FORTRAN simulation on an IBM 7090 to verify the design. Now the president and CEO of The Mathematical Analysis Company, he uses MapleSim to reduce the time it takes to develop physical models and prototype control systems. "MapleSim saved me many hours of work because the model maps onto the topology of the physical system and the dynamic equations do not have to be developed by hand," he said.

Leading Car Manufacturer Renault Solves Unwanted Engine Noise and Vibration using Maple

When an engine stops, several engine components take part in the process. Components can produce unwanted noise and vibrations when the engine slows down, which can lead to their deterioration. Jean-Louis Ligier, a Research and Development manager at Renault, and his team were tasked with determining the sources of these noises and vibrations in a 2.2 liter 4-cylinder turbo diesel engine. They found Maple to be the most efficient tool to model the engine and determine the source of the unwanted noise. More importantly, they also used Maple to determine a solution to the problem.

Maplesoft Webinar Series
MapleSim Training
Wednesday, April 22, 2009 2:00 pm ET.



This MapleSim Training Webinar is a 1 hour webinar that will include a basic introduction to the modeling environment found in MapleSim as well as a walk-through of the "Getting Started" tutorial. It will briefly cover how to use the new Dynamic Systems package found in Maple 12 to analyze equations from MapleSim, and will also touch on advanced multibody system modeling, as well as the basics of how to create a custom component for MapleSim using the "Custom Component" templates. No prior knowledge of MapleSim is required.

Optimization and Analysis Using Maple
Tuesday, April 28, 2009 2:00 pm ET.



Many scientific and engineering applications have to obey tight performance tolerances. Initial designs are often sub-optimal, and to arrive at better operating conditions, manual iterative processes using, for example, calculators or spreadsheets are applied. This can take many hours, or even days. Often the solution obtained through such processes is still far from adequate. Over the last few decades, software tools boasting advanced nonlinear systems modeling and optimization algorithms have become significantly simpler to use, and no longer require specialized knowledge; this has accelerated the productivity of technical professionals across all domains. With Maple, you can take the result of over twenty-five years of continual investment in basic research and design to better model and optimize scientific and engineering designs in less time. This webinar will demonstrate, through several applications, how Maple provides an easy-to-use environment for advanced modeling and optimization.
