For structural engineering problems, when I multiply a force (N) by a distance I generally want the answer in (Nmm) or (kNm) or units of that form. Yet Maple simplifies the result to Joules, which doesn't mean a whole lot to me when I'm trying to find stresses and strains in structural members.

My question is, how can I define my own set of units that I'm comfortable with instead of having to accept the default Maple units? I'm not having a lot of success customising units with Maple.

GMP is now deeply integrated into Maple - which I consider to be a good thing. But it appears that compiler writers are doing a bad job (see the first paragraph on GMP's home page) In other words, unless you carefully make sure that you have compile GMP properly, it is entirely possible that you end up with a buggy library. Very scary stuff.

To all,

I am trying to carry the units through an engineering calculation; however, after loading the Units package and specifying the 'FPS' system I am not getting the results I expected. Most likely I am at fault - syntax, format, etc. - so I have attached the worksheet in the hope that someone can diagnose the mistake (it starts in the Example 1 section). Thank you for your assistance.

In a previous comment, J. Tarr asks "what is Maple primarily intended to do?", and suggests that I might have something to say on the topic.

Just a friendly reminder,
Regards,

I was just wondering what a good book to learn engineering related mathematics with maple would be? There's one on the website of maplesoft but 125 seems a lot to pay for a book I'll use just for fun. So do you guys have any suggestions?

Hello!
So glad to become a part of this community, I am loving Maple.
So here is my question:
I know c++ fairly well (need to freshen up) and the same idea with Java, Ive seen I can incorporate languages into Maple, or so it seems. What type of things am I capable of doing? And along those lines, any suggestions to what path to take in order to learn such powerful tools?
I am currently working on a bachelor/masters in engineering and would love to know Maple better then I do my own Fiance (just dont tell her).
Thanks in advance!

can I change the behavior of maple to not represent 1/sqrt(2) as sqrt(2)/2? I guess in a mathmatician's view this is a simplification, but not from an engineering standpoint.
also, if I perform combine(sqrt(2)/(sqrt(m)*sqrt(k)),radical,symbolic) I get sqrt(2)*sqrt(1/m k) instead of the desired sqrt(2/(k*m))..is this related?
I'm sure there is a nuance that I am not getting...

Hi;
I am Abdul-Kareem from Iraq. I have BSc in computer since and BSc in electrical engineering. Now I am student in computer engineering to get MSc degree in Information Technology engineering. My research is "Design and Implementation a Multicast Routing Algorithm for a Network".
Please I need more information about my research and the related topics. Thank you .
Best regards.

Fedderik van der Bos created a worksheet for the Finite Element Method that is available in the download section for engineering applications; problem is, it uses a maple package (FEM) that is not posted on the site. The application is dated 2000. Does anyone have a copy of this package?

Is there a way to find out the rate of decay of function f(x) when x-> +infinity?
Hi all,
I just wanted to use this real-world engineering problem to practice problem-solving using Maple.
Suppose I have a function f(x) (probably complex valued),
how to find out its rate of decay as x approaches +infinity?
I used "limit" but it will give me a value, not a functional form.
I already knew my function has a limit =0 at x=+infinity.
And it is of fast decay.
I would like to bound the limiting behavior of f(x) by exp(-alpha*x) for some suitable constant alpha.
Is there a way to handle this in Maple?

Hi all, I am asking this for my engineering friend.
We've posted on Maple newsgroup and we just heard that here is another place where Maple experts appear, so we posted it again here to seek more advice -- because we have a struggling problem which annoyed us for several days already! Thank you!

Here is what I want to compute:
t22 := Re((1/2*(a^2+2*sigma2*(c+g*(ee+i*v)))^(1/2)*exp(.5*a*t)/
(1/2*(a^2+2*sigma2*(c+g*(ee+i*v)))^(1/2)*cosh(1/2*(a^2+2*sigma2*(c
+g*(ee+i*v)))^(1/2)*t)+.5*a*sinh(1/2*(a^2+2*sigma2*(c+g*(ee
+i*v)))^(1/2)*t)))^(2*a*xbar/sigma2))
Assuming all variables are real and positive...

Having looked recently at a suite of engineering software in use, I wondered whether engineers would need maths for much longer. Of course they’ll always need sufficient for business purposes, but my guess is maths will become unnecessary for engineering in much the same way as it’s unnecessary for weather forecasting. There would probably be a residual role for maths in engineering research, but not in the mainstream, and that would have huge implications for schools and universities. How do those engaged in teaching maths to budding engineers see the future?

Iam a Student in the faculty of engineering Petroleum department.
Iam Studying Oil Reservoir Simulation which havs many models.
Iam Studying the mathematical modeling of those reservoirs.
In this modeling we use PDEs to model that reservoir behaviour for years
we devide the reservoir into grid blocks each of its special dimensions and parameters
so for each grid block there are 3 phases which are oil, water, and gas equation (one for each phase of them)(Matrix Dimension = No. of phases * No. of grid blocks) in addition to the other parameters
there are some elements of the PDEs which is function in more than one parameter

**NEWEST VERSION OF MAPLESOFT’S FLAGSHIP PRODUCT DRAMATICALLY IMPROVES USER EXPERIENCE**

*Maple 11 is the Ideal Tool for Engineers and Scientists to Streamline and Increase Quality of Analytical Work*

**WATERLOO****, CANADA****, January 8, 2007 — **Maplesoft™, the leading provider of high-performance software tools for engineering, science and mathematics, announced a major release of Maple™, the company’s flagship product. Maple 11 features enhancements to its smart document interface, strong computation engine, and connectivity capabilities. The result is a product that provides users the necessary technology to reduce error and dramatically increase analytical productivity.

With Maple 11, the company is advancing the revolutionary technical document interface technology it introduced two years ago. The new release combines the world’s most powerful mathematical computation engine with an intuitive user-interface that eliminates the learning curve so common with other mathematical software. Its smart document environment automatically captures all technical knowledge in an electronic form that seamlessly integrates calculations, explanatory text and math, graphics, images and sound, and more. These concise live documents can be reused or shared across the organization.

“We initiated a radical change in the industry when we launched Maple 10 with its superior technical document and knowledge sharing capabilities”, said Maplesoft CEO Jim Cooper. “It changed the way people worked and Maple 11 represents another important leap forward in this direction. It is the leading tool for engineers and scientists to streamline and increase the quality of their analytical work. It also represents Maplesoft’s commitment to transforming the way our customers use technology.”

Maple 11 is supported by an extensive range of products for various industrial applications including automotive, aerospace, electronics, energy and finance. Companion products include automatic model generation, optimal design tools, intelligent control design, reference e-books, and more.
