MapleSim 2016 is here!

MapleSim 2016 provides variety of improvements to streamline the user experience, expand modeling scope, and enhance connectivity with other tools. Here are some highlights:

  • Collapsible task panes provide a larger model workspace, so you can see more of your model at once.
  • Improved layout ensures the tools you need for your current task are available at your fingertips.
  • The expanded Multibody component library now supports contact modeling.
  • A new add-on library, the MapleSim Pneumatics Library from Modelon, supports the modeling and simulation of pneumatic systems.
  • The MapleSim CAD Toolbox has been extended to support the latest versions of Inventor®, NX®, SOLIDWORKS®, CATIA® V5, Solid Edge®, PTC® Creo Parametric™, and more.
  • The MapleSim Connector, which provides connectivity to Simulink®, now supports single precision export of S-functions so you can run your MapleSim models on hardware that only supports single precision.

See What’s New in MapleSim 2016 for more information about these and other improvements.



Environment: Maple2015, MATLAB_R2014b(MacOSX10.8.5), 2015b(MacOSX10.11.4) was successfully completed (log tells us), but when MATLAB were booted, following error messages appeared and symbolic operations of maple failed. 

This would be closely related to maple installation on MATLAB as such errors never occur for clean install of MATLABs and looks independent on OSX versions. Now javaforosx.dmg in use by instruction of Maplesoft.  Something wrong is in Maple2015. Note maple-MATLAB link works normally.

Please provide us with direction of how to fix it hopefully by Maplesoft professionals.

Hi everybody,

I have some experimental data from an oscillating system (time domaine) and I would like to get an approximation of the damping ratio (zeta). I have already try to use the half-power band width method with the vibrationdata Matlab package designed by Tom Irvine. But I would like to double-check the result with another method.

I found several methods in this paper and I would like to try to do the curve fitting method with the Curve Fitting Toolbox of Maple or Matlab (R2014b) (2.2.2 Curve fitting in the paper). data.txt

It's the first I use this Toolbox with a custom equation, so, I do not really know how to do it with my sample data.

Can anybody help me with this ? I have attached the .txt file sample data to this post.


We have just released a major update to MapleSim 2015. MapleSim 2015.2 provides a variety of enhancements that make it even easier to create, simulate, and analyze your multidomain, system-level models, including:

  • Advanced diagnostic tools that help you identify the source of problems in your models and simulations, and improve their efficiency and robustness
  • Over 50 new components in the magnetic, thermal, electrical, and signal block libraries
  • A new connections manager that makes it easier to keep track of connections and port variables
  • And more! See What’s New in MapleSim 2015.2 for more information about these and other improvements in MapleSim.


We have also updated and expanded the MapleSim 2015 family of products:

  • The new MapleSim CAD Toolbox, which is available as a separate product, helps engineers understand and improve their mechanical designs by making it easy to import CAD models directly into MapleSim and understand how they behave as part of a larger system.
  • MapleSim Connector, for connectivity with Simulink®, and the MapleSim Connector for FMI both generate code that provides more detailed run-time error reporting to assist in trouble-shooting on the target platform
  • Updates to the specialized component libraries MapleSim Battery LibraryMapleSim Driveline Library, and MapleSim Tire Library provide improved modeling power and scope


This update is being distributed through the automatic Check for Updates system, and is also available from our website. See MapleSim 2015.2  for details on obtaining this update. This new MapleSim release is available immediately on Windows and Linux, with a Mac version following in the coming days. 



I have been puzzled by a matlab toolbox problem for a long time. How can I get Maple notation in matlab output?

Both "Input display" and "Output display" in Tools-->Options-->Display was changed from "2-D Math notation" into "Maple notation". And the output in Maple is indeed Maple notation like this:maple output

But the output in matlab is also 2-D notation like this:matlab output

when copy it to Matlab or Maple as input, it become the wrong issues like this:wrong style

How can I output Maple notation in matlab? The version is Maple 18 and Matlab 2014b, respectively.



Does the installation of Maple toolbox for matlab removes MuPad in matlab? 

Now when I type in mupad in matlab, it says undefined function.

Is there a way to keep both?

Hi Everybody,

I installed the Maple Toolbox for matlab and tried to run my old code.  For some reason, maple('restart') will cause Matlab to lock up.  Any ideas?

Windows 7 64-bit.  Matlab 2012b 32-bit, Maple 18 32-bit

i have a corei7 laptop and i want maple to use all of my cpu cores in paraller,what should i do exactly ? in there anyway to use them without using grid computing toolbox ? or how to manage it with grid computing toolbox? i want maple use all of my cpu power during computation, tnx for help 

another interesting bug in mapleprimes, when i created new tage , i face this error : 

Only users with at least 250 reputation can create new tags, please remove or replace these tags: computing !

Maplesoft regularly hosts live webinars on a variety of topics. Below you will find details on some upcoming webinars we think may be of interest to the MaplePrimes community.  For the complete list of upcoming webinars, visit our website.


Hollywood Math (with more new examples!)

Over its storied and intriguing history, Hollywood has entertained us with many mathematical moments in film. John Nash in “A Beautiful Mind,” the brilliant janitor in “Good Will Hunting,” the number theory genius in “Pi,” and even Abbott and Costello are just a few of the Hollywood “mathematicians” that come to mind.

Although the widespread presentation of mathematics on the silver screen is not always entirely accurate, it does serve as a great introduction to the study of mathematics in general. During this webinar Maplesoft will present a number of examples of mathematics in film. See relevant, exciting examples that you can use to engage your students.At the end of the webinar you’ll be given an opportunity to download an application containing all of the Hollywood examples that we demonstrate.

Applications of Symbolic Computation in Control Design

You may already use Maple and/or MapleSim within your organization to solve various problems, but did you know that they have capabilities for control design as well? In one of our upcoming featured webinars for this month, we will explore the Control Design toolbox including the ability to extract symbolic equations of plant models, perform symbolic linearization, design symbolic controllers, and generate very fast code for HIL testing.

The following examples will be demonstrated:

• PID Control

• LQR, Kalman filter design

• Gain scheduling

• Feedback linearization

MapleSim 6.4 includes more powerful tools for creating custom components, performance enhancements, and enhancements to the model generators for Simulink® and FMI. 

We have also made important updates to the MapleSim Control Design Toolbox. This toolbox now offers a more complete set of algorithms for PID control, new commands for computing closed-loop transfer functions, and numerous improvements to existing commands. These enhancements allow engineers to design a greater variety of controllers and controller-observer systems while taking advantage of the greater flexibility and analysis options available through the use of symbolic parameters. 

See What’s New in MapleSim 6.4 and What’s New in the MapleSim Control Design Toolbox for details.

I want to sovle two equations given as a function
G1 and G2
G1 is defined as
function y = G1(x)
y = (2*x*log(2*x)+(1-x)*log(1-x))+(.0009*x*(1-x));
G2 is Defined as

function y = G2(x)
y = x*log(x)+(1-x)*log(1-x);

when I solve the wquations using code
syms x1;
syms x2;
following error occur

??? Error using ==> sym.solve at 73

While looking over some old Maple 9.5 applications I came across two applications requiring the HPC Grid computing toolbox for maple. 

Now that parallel computing is becoming the norm and parallel code tools are included with newer Maple versions.  Has this toolbox just been integrated into Maple?  or are they two totally different entities altogether.  I am sensing the toolbox is to deal with multiple computer systems as the parallel code tools...
