I modelled a telecamera and line follower sensors in Maple in order to calculate the "error" for my PID controller. Know i would like to share this information with the PID in MapleSim but I have no idea how to do it. Is there a way to import maple libraries into MapleSim?




I am trying to download some MapleSim Robotic models from the Maplesoft website but I have 'Invalid File Format' error. Could you help please?



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 have created a model for a robot in Solidworks and have imported it into Maplesim using the CAD toolbox. The problem I have is that the robot has 3 arms that are supposed to come together on a central piece pictured below in figure 1, but attempting to simulate the model with all arms connected with a revolute joint as in figure 2 yields an error that says "The system is underdetermined" the location of the error is main.

For the purposes of the image below I only connected one of the arms, this allows Maplesim to run the file successfully.

figure 1 showing the central piece that the 3 arms are supposed to connect to.


Figure 2 showing the problem revolute joints circled in black, the error at the bottom and the setting of the revolute joint on the right.


Essentially my question is how do I get the model to work? I apologise if this problem is not terribly well demonstrated, this is my first post onto this forum so I am not sure of all the standards.

Dear MapleSoft,


Would it be possible you once design a MapleSim webinar for users with more emphasis on Modelica (language, examples, etc.), on how to build more complex custom components, not just a simple DC motor? I think this would be very useful and could extend / enhance the use of MapleSime even more.


Tx in advance,

best regards

On maplesim how plot the transfer funtion vs frequency for the public domain example tuned mass dumper?

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! 

Hi, I am a student and a recent new MapleSim user. I downloaded the MapleSim Wind Turbine Vibrations model from the Model Gallery ( 

I do not understand the model diagram, and find it difficult to visualize the way all the components work. Also, how can I change the mass moment of inertia of each blade? 

This is my first question, apologies if it sounds silly. Thank you :)

I am a college student that is aspiring to become a theoretical theorist. I have postulates that are not in mathematical form yet, and I would like to use a program that can help with this process. I am new to the usage of Maple products, and I have questions. Is it possible to use Maple in this way, before getting to the difficult calculus steps? Can MapleSim or Maple Physics, perform simulations, or models of physics calculations?

Thank you,

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.
