When I run a simulation (i.e. Double Pendulum Example) MapleSim crashes with no errors or dialogues - completely shuts down. The simulation seems to compile ok, then as the plots are opening it crashes. My video card driver is up to date. Anyone know how to fix this?


Here are some tips and tricks - ranging from keyboard shortcuts to the newest features - that will help you get the most out of MapleSim 2015.

  1. Quickly run your simulation by pressing F5. Similarly, toggle between the Main Window and Visualization Window by press F6.

  2. Maintaining an organized and clean model layout is made easier by using the Reroute Connections tool. Select the connection lines or components and press CTRL+D (or using the Edit menu, Reroute Connections) to have MapleSim automatically reroute the connections.

  3. While creating your MapleSim model, components and connections can be enabled or disabled by selecting the desired item(s) and using the disable/enable button (  ) or the keyboard shortcut CTRL+E.

  4. Use the Model Tree palette in MapleSim to help manage, navigate, and search a model quickly. Items within the model tree include: components, probes, parameters, and attachments. Simply select the desired view using the drop-down menu. The Model Tree palette is found under the Project tab.

  5. Automatically remove any unreferenced subsystems or custom components using the Prune Model tool. Especially useful for large models or models with multiple modifications, this tool will automatically identify and removes unused shared subsystems or custom components that appear within the Definitions tab, Components palette. The Prune Model function can be performed by clicking the Edit menu, and selecting Prune Model.

  6. Set the MapleSim’s Visualization Window to always on top by toggling the anchor button (  ) in the upper left corner of the Visualization Window.

  7. Automatically scale the model diagram to fit in the viewable area by pressing CTRL+T to gain a complete look at the model. Then return to a default zoom by pressing CTRL+0 (zero). This is also accessible using the View menu.

  8. To group components into a subsystem, select the desired components, right-click and select Create Subsystem or press CTRL+G.

  9. For quick access to get help on a particular component, right-click on it and select help. Similarly, selecting a component within the workspace and pressing F2 will bring up the help page for that component.

  10. View the Modelica code behind the visible system/subsystem/component, click Code View (  ) in the Navigation Tool bar. Then, to switch back to Diagram Mode click the icon (  ) in the Navigation Tool bar.

  11. Automatically compare two models by using the compare tool, found under the Tools menu Compare Models.

  12. Attach important files to a MapleSim model to keep content in one place. Attachments can be Maple worksheets or others such as pdfs, Excel, Word, STL files, etc. These files are found under the Project Tab, Attachments palette. Attach a file by, right-clicking the category and selecting Attach File or clicking the Edit menu Attach File.

I hope you find these useful! Do you have any tips that you would add to this list?

in maplesim 7

when run example below

got error in linear_string and linear_string2

prototype must be a structured record type or a record, but received squeezed




There is a problem with the modelica code for custom component named CorneringForce
Regenerate or delete this component to correct this porblem....


i click the web said USD99

but after click into it, academic version is USD1,555

there are commercial version, academic version , what are difference?

i see that there are self balance robot and humanoid walk robot

what are the specification of size, length of components are they?

if simulate robot hand which has a string make a tension to grip object

what kind of string is it? where can buy robots components which fit the simulations it do?

will maplesoft cooperate with 3D printer to fit the reality of robots?


I have just updated maplesim to the last version (maplesim2015).

On the multibody examples of the maplesim2015 library, I didn't have any problems.

However, when i try to launch a simulation on a model i have made with a previous version (which worked before I use maplesim2015), i meet this problem :

May you help me to make the troubleshooting ? For the moment, I didn't manage to locate the error.

Do you have some ideas about this mistake ?

Thanks a lot for your help.

Does anyone know how to achieve the state transition of a prismatic joint between active and passive in MapleSim? Recently, I want to realize such a state transition of a prismatic joint. Specifically, during a simulation, the joint can either be motion-actuated or passive according to some conditions. Actually, I tried to use SimMecahnics, but I failed. Hope anyone can give me some constructive suggestions. Many thanks!



Is there a way to export all of the equations (from MapleSim) including the casual equations? I used Multibody Analysis template and Equations template but it only exports the acausal equations.


Your help is really appreciated.

Hi all,

How to build an uneven ground by MapleSim?

I want simulation a car runnung on this uneven ground.

Is there any method , proposal , orientation, or any thing can help me


Thank you

Hi all,


I met a problem while using the MapleSim7.

When I increase the plot points (which can be modeified in the setting tab) to get more accurate solution,

MapleSim does not show the simulation results (ex. graph) even though the simulation has finished.

MapleSim message only says "Done Simulating", but does not show the results.


When I set plot points "10000", I could obtain the results. However when I set "30000" for plot points, 

I couldn't get results.


What is the problem and how can I obtain the results with many number of plot points?


Hi, I build my simulation system in MapleSim, using the module 'Stepper Permanent Magnet' like this


But when I run this system, I get the followiing error:

System is underdetermined


When I delete the part about 'Stepper Permanent Magnet', the system runs well.

How to solve this problem? How to use 'Stepper Permanent Magnet'?

The Help file of MapleSim cannot proviod such help information.

Thank you.







I want to simulating a mulitibody system, similar circular motion.

schematic diagram:




Why the ball cannot keep on the circle?




is there a way I can use data (variables) from Maple environment in the Maplesim environment. 

I have a scirpt in maple that generates the robots joints angles and need to use them in the 3D robot built in maplesim. I know I can export/Import data, but this sounds redundant. Is there a way to simply use an input block as a source of the data in maplesim and have the variable name generated in maple used int. Similar to what Matlab/Simulink does.. 





i have some problem when iuse the digital libray with the delay components:

i have this error: delay variable not found in dependent variable list, [`Main.TransportDelay1.x`(T)]

it seems that the delay function in the modelica language is not well treated in MapleSim . At this level:


    y = if 0 < delayTime then if delayTime <= time then x_delayed else y0 else pre(x);
    x_delayed = integer(delay(x, delayTime));
end Modelica.Electrical.Digital.Delay.TransportDelay;


Thank you for your help.



Maplesim 7.0(1) installer looks for Maple 18 installation.  Will Maplesim work with Maple 2015?

If not, what is the expected date of making both products compatible?



Hi! I'm having trouble with the MapleSim "Equation Extraction" template. I have an extremely simple dynamics scenario with RigidBody at a particular position in a world; when the simulation starts, the body should simply start fallin with a constant acceleration, and I'm looking to extract kinematic equations for this situation.

However, the problem I have with the extracted equations is that they contain some rotational dependent terms that I wish to avoid - a lot of sines and cosines with arguments that I actually cannot match up to any variables in the model, or when I enable quaternion representation, terms like this:

What I don't understand is what exactly these rotation terms represent. The object should be falling straight downwards, and gravitation should be applied straight downwards, and when I start the simulation it does run through, also indicating that there should be no unbound variables. I'm not sure exactly what parameters in the Modelica model do they correspond to? I did not find any such angles in the object settings. And can I ask MapleSim to generate equations without these unbound rotation variables?
