When I create a component, here a label component, and set a name property and then click OK, that name seems to go into some list never to be erased. If I then delete the first name and put in a new name and click OK. thus saving it, and the then try to use that name again on a different component, I am told that the name is already in use. Well, no existing component has the name, but it is still in Maple's list of components. If I go to edit an action for any component and input %+command completion, I get a list of components which includes the deleted name which does not belong to any existing component. Since the name is on this list, I cannot reuse the component name.

How do I clean up this erroneous list of component names, so that a mistake in naming one component doesn't forever prevent me from using it on the component for which it was intended?


Hi! I'm trying to use MapleSim 7 to simulate some very simple physical situations, however after great many hours spent at this, I'm still unable to convince MapleSim to load and run even the simplest Modelica models, like:

model Main
  Modelica.Mechanics.MultiBody.Parts.Body o(r_CM = zeros(3));
  inner .Modelica.Mechanics.MultiBody.World world;
  o.frame_b.f = {0,-9.8,0};
end Main;

It will report that o and world are "unknowns" and apparently does not recongize Modelica.Mechanics.MultiBody.Parts.Body nor Modelica.Mechanics.MultiBody.World. Do I need to do some extra steps to import extra libraries or enable some non-default components?  I went through various YouTube and other tutorials and didn't find a mention of anything.

When I look at some examples, often they refer to things like Maplesoft.Multibody.World - but these are proprietary Maple packages, and I need my code to use standard Modelica. Does this mean that MapleSim cannot run generic Modelica code like this?

I also tried running e.g. and some other examples, with absolutely no success either. I'm quite confused because MapleSim has a lot of advertising about Modelica support... :-(

Currently calculations: equations, regression analysis, differential equations, etc; to mention a few of them; are developed using traditional methods ie even are proposed and solved by hand and on paper. In teaching our scientists and engineers use the chalkboard as a way to reach students and enable them to solve their calculation. To what extent Maple contributes to research on new mathematical models applied science and engineering ?. Maplesoft appears as a proposal to resolve problems with our traditional proposed intelligent algorithms, development process, embedded components, and not only them but also generates type applications for Apple ipad tablets signature. Based on the computer algebra system Maple Maplesoft gives us the package which works exactly like we were on our work. I will show how mathematics is developed from a purely basic to reach modeling differential equations applied to education and engineering. Also visualizare current techniques for developing applications for mobile devices.

In this work we show you what to do with the programming of Embedded Components applied to graphics in the Cartesian plane; from the visualization of a point up to three-dimensional objects and also using the Maple language generare own interactive applications for touch screen technology in mobile devices techniques. Given that computers use multicore and designed algorithms that solve calculus problems with very good performance in time; this brings programming to more complex mathematical structures such as in the linear algebra, analytic geometry and advanced methods in numerical analysis. The graphics will show real-time results for the correct use of the parallel programming undertook to bear the procedural technique is well suited to the data structure, curves and surfaces. Interaction in a single graphical container allowing the teaching and / or research the rapid change of parameters; giving a quick interpretation of the results.

I am sure that with this vector file with embedded components will learn how it works the vector operations. The code is free and can be modified to be improved. Forward engineers.     (in spanish)

With the package VectorCalculus we can study the speed and acceleration to their respective components. Considering the visualizaccion and algebraic calculations and to check with their respective commands. Both 2D and 3D.

What I'm looking for is a good text for my Embedded Components interactive mathematical designs. I have several books of Maple but speak little of Embedded Components. MapleCloud community hope I post up a book. It is very poor on "The Maple Help System" so I need a good text.

Hi, I use Maple 13 and have this issue to solve.

In an archive.txt there is the following Vector:



I have a system consisting of a multi-body system and various modelica/maple custom components. The problem is whenever I re-run the simulation even though all the simulation settings are same, the simulation results are inconsistent. There should be no difference between each simulation as all the parameters/settings are same. I am attaching two pictures which are both obtained from two successive simulations


The Locator object is a nice piece of Mathematica's Manipulate command's functionality. Perhaps Maple's Explore command could do something as good.

Here below is a roughly laid out example, as a Worksheet. Of course, this is not...

Good afternoon

i have problem when i am using components.

i want to solve a determinant equation and show in MathContainer4


thank you for your help



Another feature added to Maple 15 partially in response to the MaplePrimes forums is the new/improved ?HTTP package.  It provides one-step commands for fetching data from the web: much simpler than using the ?Sockets package directly. In most cases, the command ?HTTP,Get is what you would use:

 (s, page, h) := HTTP:-Get(""):

The above fetches the HTML source of a page from Wikipedia and stores it as a string 'page'. The other two outputs are 's', and integer HTTP status code and 'h' a table of the headers returned in the HTTP response from the server.  Compare this to the amount of code needed to fetch data in my Baby Names application for Maple 12, for example.

Now that Maple 15 is out, I thought I should share this little application I made: It is an application partially inspired by the BMI tracker in Nintendo's WiiFit application; you could easily use it to track a weight loss goal. But it could also be used to track other quantifiable goals. I am posting it here mostly because it takes advantage of two new features in Maple 15.

To the Ineffable All,

     I don't understand what MapToBasis is doing to get the results shown in the example program.  Specifically, why are the x-y components interchanged and a sign added?  It seems to plot OK, but the components of the vector appear wrong to me. 


Hello, MaplePrimes!

I want to create a custom component to model dynamics of a movable pulley, which can rotate and move along some direction (translational motion). I’ve got dynamic system, which describes both motions of a pulley. Some information about this dynamic system:
