A Mathematical Software for All Serious Researchers
http://www.mapleprimes.com/posts/201099-A-Mathematical-Software-For-All-Serious?ref=Feed:MaplePrimes:Tagged With engineering
<p>For the past thirty years, I have used several mathematical packages for problem solving and graphing. It all started with spreadsheet software that really helped speedup calculations compared to calculators. As many people do, once I had one tool I then started looking for another that would offer even more capabilities and features. I tested several of the very early math software but none really did all that I wanted until I came across Maple while I was working at SPAR Aerospace in Canada. For me, the rest is history. As long as I had a copy of Maple, it was all that I needed.</p>
<p>On occasions when I did not have a copy of this amazing software, I resorted to spreadsheets once more to complete fairly large and complex projects involving large databases and large numbers of calculations, especially when performing What-If scenarios. One distinct disadvantage of using a spreadsheet was the cryptic form of equation writing. I had to divide one long equation into several sections in different cells and then add them all up, which clearly is not good for documentation of the calculations. It is also very confusing for other engineers to know what that equation is or what it does. The development of the full engineering spreadsheet took months to complete, debug and verify. During this process, when I had errors, it was often very difficult to track exactly where the problem was, making the debugging process time consuming and sometimes very frustrating.</p>
<p>Having worked with Maple before, I remembered how easy it was to enter equations in a very familiar, readable math format. The real power of this software is that it allows you to write the equation(s) anyway you like and solve for any given parameter, unlike spreadsheets where you have to solve the problem first, by hand, for the parameter you want and then get the spreadsheet to calculate the value. I remember one time a few years ago when I wrote nine or ten simultaneous differential equations all in symbolic form and asked Maple to calculate certain parameters in a fully symbolic form. To my utmost disbelief, the answer came back within few minutes. With results in hand, I was able to quickly finish my research, and the results were published at PCIM Europe 2005 in “Distributed Gate ESR and its Effect on Shoot Through Performance at the Die Level”. I would never have gotten the results I needed if I was using a spreadsheet.</p>
<p>Even with much simpler systems of equations, finding solutions with a paper and pencil was never an easy task for me. It took a very long time, and even then there was no guarantee that I did not make copying errors, accidentally leave out a term, or make a calculation error. After I found the correct solution, I then had the problem of plotting the results, which I often needed in 3-D. Plotting allowed much deeper insights into the interdependency of all the parameters and made it easy for me to concentrate on the important ones without wasting any time. I was very happy when I could pass all these tasks onto Maple, which could do them much faster and more reliably then I ever could. Maple is a software that allows me to go beyond routine engineering calculations and gives me the tools to reach levels of insight and understanding that were completely out of reach of the average engineer until a few years ago.</p>
<p>For the record, I have no business affiliations with Maplesoft. I’m writing this article because Maple makes such a difference in my work that I feel it is important to share my experiences so other engineers can get the same benefits.</p><p>For the past thirty years, I have used several mathematical packages for problem solving and graphing.

http://www.mapleprimes.com/questions/203559-How-Do-I-Solve-A-System-Of-Nonlinear?ref=Feed:MaplePrimes:Tagged With engineering
<p>Hi,</p>
<p>I'm an industrial engineering student who's running into problems with solving a simple system of non-linear equations.</p>
<p><img src="http://s000.tinyupload.com/?file_id=00942426057117185286" alt=""></p>
<p>Why do I get this error when issuing the solve command? I'm pretty sure I'm only passing two lists into the function?</p>
<p>Thanks a lot in advance,</p>

<p>Hello,</p>
<p>for my mechanical engineering studies we have to optimize an engine during a workshop. Therefore we have to use a numerical dsolve to solve the equation of motion. I have to get the maximum bearing reaction for a constant rpm. In order to get this I can't think of anything else but use the dsolve solution and use it in maximize.</p>

<p> </p>
<p>The last three lines bear my problem: I need to use a algebraic function for y(t) but I don't know how to get it from a numeric dsolve. The difference between the two forces at the end is a solid bearing vs a spring/cushion system. The spring/cushion system allows a vertical movement y(t) restricted by the spring force (F_F(t)) und the cushion force (F_D(t)). Because of the extra vertical movement the inert forces change and the inert force of the whole engine (T_Motor(t)) is added.</p>
<p>How can I solve this problem?</p>
<p>PS: Please excuse any bad english and unclear formulations but this is my first post here and english isn't my first language.</p>146365Sat, 27 Apr 2013 13:51:23 ZXelN4g4XelN4g4Entering reference values in tables

<p>MapleSim has seen a rapid evolution since its inception in 2008 as a multi-domain system-level modeling and simulation environment. Market response has been outstanding: Maplesoft has been working with an expanding list of key industry players such as <a href="http://www.maplesoft.com/company/publications/articles/view.aspx?SID=125666">AISIN AW Co., Ltd.</a> and <a href="http://www.maplesoft.com/products/toolboxes/br_auto/">B&R</a>, while major customers like <p>MapleSim has seen a rapid evolution since its inception in 2008 as a multi-domain system-level modeling and simulation environment.

The latest release, MapleSim 6, delivers major enhancements along all three pillars of innovation that this product has become known for: Modelica, advanced analysis, and fast HIL code.</p>
<p><a href="/view.aspx?sf=137068/442274/MapleSim_Core_Fina.jpg"><img style="display: block; margin-left: auto; margin-right: auto;" src="/view.aspx?sf=137068/442274/MapleSim_Core_Fina.jpg" alt=""></a></p>
<p>If there had been any question about the <a href="http://www.mapleprimes.com/maplesoftblog/32948-Does-Modelica-Matter">potential of Modelica</a> as the standard open model description language when we started the MapleSim project in 2005, there can be no question today. Modelica is ubiquitous in many parts of Europe and enjoys rapid growth of its user base around the world, notably in both North America and Japan. In MapleSim 6, you will find a friendly Modelica environment that gives you access to the full power of the language. At the same time, we have taken great care to keep MapleSim easy to use and learn, leading to productive usage as quickly as possible. For example, while you can now browse the Modelica code for any library component with just one click, you can also see all definitions and equations of that component at a glance without having to follow chains of inheritance manually.</p>
<p>MapleSim's interactive analysis environment, based on Maple, is certainly unique among physical modeling tools. Template documents provide easy access to common tasks like building custom components, performing optimization, or Monte-Carlo analysis. The true power, however, comes with the API, which gives you full command-based control over setting up, running, and analyzing models and simulations. Combined with Maple's computational capabilities, I have seen the API perform sophisticated parameter sweeps - distributed in parallel over all the cores of your machine. Another example is a multi-body model, where Maple was used to compute explicit (symbolic) formulas for inverse kinematics and inverse dynamics. Those formulas were then plugged into a MapleSim model using a custom component to yield blindingly fast simulations. The possibilities with the MapleSim API are virtually endless, but at the same time easily accessible due to the open nature of the Maple environment.</p>

<p>The third pillar for MapleSim is the ability to generate very fast (and royalty-free) simulation code for HIL/SIL. This is another example where the underlying symbolic computing engine becomes a distinct advantage. Being able to simplify and optimize at the equation level allows MapleSim to consistently outrun its competitors. For hardware-in-the-loop simulations, execution speed makes the difference between being able to run a model in real-time or having to compromise on fidelity. MapleSim's automatic simplifications and optimizations are loss-less and yield simulation code that is typically a factor of 3 to 20 times faster than using other tools. In addition, symbolic computing techniques in Maple pave the way to further model reduction, for example for applications like model predictive control.</p>
<p>As a whole, MapleSim 6 offers all the ingredients to tackle today's most sophisticated engineering challenges across a large variety of disciplines and industries, and has the potential of making a significant difference within your toolchain.</p>137068Tue, 04 Sep 2012 20:37:14 ZLaurent BernardinLaurent Bernardin
