<p><strong><span>Symbolic Computing for Engineering</span></strong></p>
<p><span>As engineering applications become more complex, it is becoming increasingly difficult to satisfy the often-conflicting project constraints using traditional tools. As a result, we’ve found there is a growing interest within the engineering community for tools that make engineering calculations transparent and capture not just results but also the knowledge and analysis used throughout the engineering workflow. Engineering organizations are achieving this goal by making symbolic techniques an integral part of their tool set.</span></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

http://www.mapleprimes.com/maplesoftblog/137068-MapleSim-6-Advances-In-SystemLevel-Modeling?ref=Feed:MaplePrimes:Tagged With engineering
<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><a href="/view.aspx?sf=137068/442274/modelica.jpg"><img style="display: block; margin-left: auto; margin-right: auto;" src="/view.aspx?sf=137068/442274/modelica.jpg" alt=""></a></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 BernardinNASA Jet Propulsion Laboratory to Land Rover on Mars on Monday

<p>Starting from Maple 15, the useful <a href="http://www.maplesoft.com/support/help/search.aspx?term=plottools/getdata">?plottools/getdata</a> command is added. It tansforms a Maple plot to a Matrix. Unfortunately, the getdata command deals only with Maple plots. The question arises: "How to get a data from bmp, jpg, tiff, pcx, gif, png and wmf formats?" This is used in medicine and engineering. Such question was asked here<p>Starting from Maple 15, the useful <a href="http://www.maplesoft.com/support/help/search.aspx?term=plottools/getdata">?plottools/getdata</a> command is added.

My answer to the question leaves much to be desired. As far as I know it, such programs are created. I would like to present a free program Graph2Digit 0.7.1b <a href="/view.aspx?sf=132559/433889/Gr2Digit.zip">Gr2Digit.zip</a> created by Vyacheslav Plisko: <a href="http://plsoft.narod.ru/digitizer.html">http://plsoft.narod.ru/digitizer.html</a>. His program digitalizes a plot, taking a prescribed step, and edits the output as required. It results a txt file.<br>Here are some of its capabilities:<br> - support of bmp, jpg, tiff, pcx, gif, png and wmf formats;<br> - scanner support;<br> - clipboard support;<br> - rotation of picture;<br> - automatic mode of maximal brightness;<br> - automatic mode of color;<br> - manual mode;<br> - edit mode;<br> - hot keys.<br>Unfortunately, the interface is only in Russian. It would be very useful to implement it in Maple.</p>
<p>PS. Not this progam, but to add its capabilities to the getdata command.</p>132559Tue, 03 Apr 2012 18:44:31 ZMarkiyan HirnykMarkiyan HirnykDisplaying calculations

<p>I have been using Maple in Document mode to provide documentation of engineering calculations according to various design standards.</p>
<p>I have been asked to provide more detail about certain critical calculations.</p>
<p>Ideally, I would want to enter the formula as a symbolic espression, then the output would begin with and echo of the expression with numberic values substituted for the variable names (ie without performing any mathematical operations), and then give the evaluated answer.<p>I have been using Maple in Document mode to provide documentation of engineering calculations according to various design standards.</p>

<p>Ideally, I would want to enter the formula as a symbolic espression, then the output would begin with and echo of the expression with numberic values substituted for the variable names (ie without performing any mathematical operations), and then give the evaluated answer.</p>
<p>The idea is to provide the reader with the necessary information locally in the document to be able to duplicate the calculation by hand.</p>
<p>It has been suggested to me that I could use print(x,y,z) to list out the values of the variables, but that just dumps out the values in a comma separated list, not a clearly indicating "x=1, y=2, ..."</p>
<p>Is there a way to tweak this using customized typesetting?</p>
<p>Anyone else trying to do something similar?</p>
