I have tried to do it by the following command "File/Modelica/Import Modelica Library" in MapleSim GUI. An error appears saying "Modelica is a reserved name".

I think you can also reproduce it by downloading the Modelica library from the following web site: "". And then importing it in the usual way by openning the file at the root directory.

I think I am missing something here, so any advise/information/minimal commentary would be greatly appreciated.

Cheers, Ovle

Hello everyone,

I am making a mobile robot simulation in the MapleSim environment and I need to create varriable (uneven) terrain, do I need an additional library for that?

If not how can I do so?

Thanks for your time!


We have just released a small update to MapleSim.  MapleSim 2016.2a is an update to MapleSim 2016.2 that includes improvements in several areas, including corrections to problems related to custom components and importing Modelica libraries. As usual, we recommend that every MapleSim customer install all available updates.  The update is availble through Help>Check for Updates and as a download from our website.  See MapleSim 2016.2a for details.


We have just released a major update to MapleSim and the MapleSim family of products. This update includes significant enhancements in the areas of model development and toolchain connectivity, including:

  • Live simulations let you see results as the simulation is running, so you can track progress and react to problems immediately.
  • A new 3-D overlay option lets you easily compare simulation visualizations by overlaying one visualization on top of another
  • Tools for revision control enable a structured approach to managing and tracking changes to your model, making it easier to manage projects when multiple engineers are working on the same model and reducing development risk.
  • MapleSim now supports direct import of models created in other FMI-compatible software, providing even greater cross-tool compatibility and opportunities for co-simulation.
  • The MapleSim Connector, for connectivity with Simulink®, and the MapleSim Connector for FMI, for exporting MapleSim models to other FMI-compatible tools, have been expanded to allow you to explore simulation results involving exported MapleSim models from within MapleSim, even though the simulation was done in the target tool.


This update is being distributed through the automatic Check for Updates system, and is also available from our website. See the MapleSim 2016.2  downloads page for details on obtaining this update.



Hello guys..

I am a master student and I am interested in modelling of six dof industrial robots. in this study, ı firtsly import autocad model into Maplesim and add revolute jont between each  two link. I want to coriolisis matrix from the model with inertia matriix . I wait your helping and thanks for your interest   

Hi everyone,

I need some help with the following error,

How can i solve this problem?

Thanks for your time

Best regards,


Hello every one,

I'm using Maple to create a compiled program of my model Maplesim. I had a error with "getcompiledProc" command, which is :

Error, (in GetCompiledProc) non-numeric initial condition for `Main.RAB.value`(t): Float(undefined)

the "Main.RAB.value(t)" represent a probe used to visualize an output of my system.

Does anybody had a such error ?
Thank you for your responses.


Dear forum users/ admins, I have some questions regarding the wind turbine vibrations model based on the MapleSim gallery. I am a new user, went through some tutorials and am currently trying to understand how the system works.


I will try to deliver my questions based on the pictures shown below:




 1. After running the model, 2 results were shown. One is "Latest Results" and the other is "zeta=0.01". Based on the images above, there is a comment that the result was dated Feb 14 2013. Is this the result on which the day the model was created? If it is, is it programmed to be in the result file everytime the simulation runs?



2. If I untick "zeta=0.01", a red graph appears, which says Latest Result. But the graphs are not labelled. How can I label this graph in MapleSim? 

3. I would also like to ask, what type of vibrations are occuring in the model, and what does the Deflection-Time graph means. Why does the deflection occur highest at 120s and then drops? Is it because the tower becomes stabilized after a while?



4. I understand that the model is run by a signal and fed into a speed component. May I know what is the f(critical) is, and how it affects the system?



5. From the Ramp signal, there is a "height" value. The pre-set value is 10. After changing this value, to lets say 50, the maximum deflections occur at a an earlier time as shown in the figure below:



6. I would like to understand how does the ramp affect the maximum deflection time that occurs.


Thank you very much!

I am working on modelling a helicopter blade. Maplesim's Flexible Beam model cannot handle composite material cross section and pre-twist angle. I need to build a custom component based on Hodges's beam model. When I use the Custom Component template, add port and choose port type, there is no "frame" type, which is needed to connect other multibody components. Is it possible to create custom multibody component? If so, how can I make it? Thanks! 


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.



Can we get it in MapleSim, not in exactly this form, but in substance? (Not in Maple)
The line of intersection of surfaces:
(x1-0.5) ^ 4 + x2 ^ 4 + x 3 ^ 4-1. ^ 2 = 0.;
x1 ^ 2 + (x2-0.25) ^ 2 + x3 ^ 2-1. ^ 2 = 0.;
(Red) rotates about an axis oX3. During rotation, the line intersects with the fixed sphere ((0., 1.5, 0 .5); R = 1.725). One of the points of intersection is drawn in green.

I have many tests to conduct on a MapleSim model. At each test simulations, I would like to change slightly some parameters.

As I have many tests to do (with different parameters), I would like to use a script so as to do like this :

Parameters test1
Launch MapleSim simulation
Store results of test 1

And so on ...

How can I do this kind of script ?

Is it possible to store the 3D animation results ?

Thank you for your help.

I'm trying to run c code generated from a simple MapleSim example (Spin Up Beam). To makes things even simpler, I set the input real expression to just time, and changed the input function in my c code to:

static void inpfn(double T, double *U)
U[0] = T;

I set all the state variables to 0 for the initial conditions. I ran the code and my output doesn't resemble the MapleSim output at all, and I'm getting errors. So my question is about the state variables, which I initially set to 0:

* State variable(s):
* x[ 0] = `Main.SpinUpBeam.FB3.uf1`(t)
* x[ 1] = diff(`Main.SpinUpBeam.FB3.uf1`(t),t)
* x[ 2] = `Main.SpinUpBeam.FB3.uf2`(t)
* x[ 3] = diff(`Main.SpinUpBeam.FB3.uf2`(t),t)
* x[ 4] = `Main.SpinUpBeam.FB3.vf1`(t)
* x[ 5] = diff(`Main.SpinUpBeam.FB3.vf1`(t),t)
* x[ 6] = `Main.SpinUpBeam.FB3.vf2`(t)
* x[ 7] = diff(`Main.SpinUpBeam.FB3.vf2`(t),t)

What do these represent for this flexible beam (FB3)? I.e. what is uf1, uf2, vf1, vf2? Should they be set to 0, or no?


For those who are running Maple and/or MapleSim on the Mac, and who may have missed an earlier question on this site, we wanted to let you know that there are some problems with running Maple and MapleSim on the new Mac OS, Mac OS X 10.11 (El Capitan). We’re working on a solution, which we expect will be ready in a few weeks. We’ll keep you posted, but in the meantime, please delay updating your Mac OS for now to avoid problems.
