i have a problem when i input this code in maple,..

how it can be error?

what the solve?

thanks for help me

the code:

> with(plots); with(DEtools); with(plottools); a := 0, 5; b := 0, 2; c := 0, 7; d := 0, 2; E := 0, 1;

I'm running a 2D parameter sweep from Maple 15 on a MapleSim 5 model. The output is stored in a 2D matrix.  I've encountered two problems:

1) when I graph it with matrixplot the z-axis values are fine but I can't figure out how to change the x-axis and y-axis values from the matrix indices to the actual values of the swept parameters. 

2) When the parameter sweep begins I get a warning about storing the values in a matrix.  Maple...

I'm looking for several challenging projects for a Calculus II course using Maple which I'll be teaching in Spring 2013.  By challenging I mean that the project will have several steps including both conceptual and computational aspects.  I'd also like them to be suitable for group work if possible.  I'd be willing to devote from 3-5 class periods for each of three or four different projects.  Our Calc I and Calc II are five hour...

I have modeled something like a rope attached to a fixed frame at both ends. Is there a way to detach one end of the rope from the fixed frame during a simulation? Is there a better way to go about this? I want to be able to release one end of the rope during the simulation.

Any advice or thoughts will help.


We have just released Maple 16.02 and MapleSim 6.01.

Maple 16.02 includes updated platform support, enhancements to the Physics package (including fixes to problems first reported on MaplePrimes - thank-you),  connectivity to the latest version of MATLAB and Visual Studio , as well as some efficiency and interface improvements. See the Maple 16.02 update page for more details.


I would like to know if it is possible to declare some variables in one parameter box (i would call it independ parameters) and other with parameters that depends on the first ones:





(for exemple)





I used MapleSim to obtain system's equation by "Equation Extraction."

In the equation, there is a strange command displayed as "preopt" and I have no idea know what this command does.

This command appears in piecewise that contains roots.

I used helps (both Maple's help and the help on the website) and googles but still don't get any idea.


Can anyone tell me what "preopt" command is?


I was just curious if MapleSim has integration capability with Zemax.

I'm interested in creating a dynamic electro-mechanical model (i.e. optical imaging on a moving system):

Zemax <--> MapleSim

If there isn't a toolbox yet, is there a workaround?


Thank you again!

Hello, I'm creating a rolling thin disk (rolling without slip) in the MapleSim, the model like the picture below (Fig. 1).



Hello. I am creating a custom component similar to the one that maplesoft has as an example (the discretized counterflow heat exchanger), but with some diff. The problem is that when i execute dyamic systems i get an error saying:

Error, (in DynamicSystems:-ParseSystemInputs) cannot match the arguments to an appropriate system

Is this a problem on my equation (something that i may have forget) or is another thing? Are the arguments type of dynamic system in the right "type"?

I am writing to request some general opinion/support. I’m new to Maple and I’m interested in analysing a pile foundation (long steel pipe driven into the ground). The pile is normally modelled as a series of masses interconnected by straight elements and the soil surrounding the pile is modelled as a series of non-linear springs acting on each of the masses.

I would like to know if this is something that can be done in Maple or if MapleSim is needed.

We have just released a free collection of Maple and MapleSim classroom materials that helps bring modern technology to any introductory course in control design. This collection includes interactive classroom demonstrations that illustrate key concepts; lab projects and assignment questions; and example models ready to be explored.  It’s been designed primarily for instructors, but students should find much of it useful, too.

Hi there,


I am trying to solve a system that has 5 unkown variables. I have 4 equation and a if statment in order to solve the system as it can be seen in the figure.

The problem is that nch4(t) and nar(t) are the input variables. If i put the IF EXPRESSION before the equation i get this...

Does maple 16  work with Visual studio 2012?

I want to simulate these contact relationships by rocking vibration as shown in Fig.1.



The two boxes (rigid body) should be contact theoretically.

However, my model did not contact.

Here, msim file is attached.
