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.


I have a very simple (possibly stupid) question. 

I am wondering if there is a simple way to model a mass on a rope (or string) in MapleSim, and measure the tension in the rope. Any suggestions would be helpful. 



I have a HOMEUSE licence including Maple 15, MapleSim 5, with Driveline and Tyre Libraries. Does anyone know when the intergated Maple 16 / MapleSim 6 will be release for upgrade?

I have been messing around with MapleSim for a while now, and I cannot find a good way to model something such as a spiderweb. I want to be able to model a spiderweb (using something like cables), and then measure the tension in the cables, and also vibrations as they travel through the cables. Is this something that I can accomplish using MapleSim? If so, what is the best way to approach this problem? Any suggestions or comments would be helpful. Thanks. 

Hi there!

I'm trying to decompose a measured force (with Force and Moment block) to visualize the three components XYZ independently, using the Force Arrow block. I tried using demultiplexers but an error occur:

connection element mismatch: connect((Main.M3_1.y[1], Main.M3_1.y[2], Main.M3_1.y[3]), /*struct*/ (Main.DFPSubsys1inst.force.r_0, /*struct*/ (Main.DFPSubsys1inst.force.R.T, Main.DFPSubsys1inst.force.R.w), Main.DFPSubsys1inst.force.f,...

Hi people!

I'm experiencing lags of about 45 seconds on the interface when trying to manipulate the blocks of my model. MapleSim becomes totally unresponsible when, for example, I make a new connection. It just happens with this model.

Curiously, when I disable an specific connection, I can manipulate the model with reduced (but yet present) lags.

For instance, my processor is an Intel Core i5.

Could someone take a look at it? I will upload the model on demand.
