Hello, I'm creating a rolling thin disk (rolling without slip) in the MapleSim, the model like the picture below (Fig. 1).



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 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.

Hi there!

Is there a way to implement a fixed delay (not the Padé approximation)? I'm using MapleSim 5. 

I tried importing the Modelica's fixed delay block, but it seems that MapleSim doesn't support the implementation...


Hi people!

Why there is not a "Modelica.Mechanics.MultiBody.Joints.RollingWheel" (different from 1-D mechanics rolling wheel) in MapleSim 5? It is previewed in the Modelica language and SystemModeler has this implementation.

Is there a way to import the model o this joint from somewhere? If not, how could I model this non-holonimic constraint in MapleSim? 


Hi there.


I build a costum component on maplesim. It has 2 inputs and several outpus, like this:


As you cant see i get an error. At this simulation the constant where is probe1 is k=4. I have good results if n=2-~3.5. But what is strange is that if instead of a constant input n=4, i use a...


I have an inverse kinematics model for a double inverted pendulum. There are multiple solutions for each joint angles due to symmetry and I have to choose the appropriate ones. I thought I can use the previous choices and compare them with the current multiple solutions, so I could choose the ones which are closer to the previous ones. However, since the double inverted pendulum moves in in both region at the equilibrium, this aproach does not work. Could you advise...


The model that i uploaded (EqQui.msim) has a component with severall output and 4 inputs, but 2 of the inputs (LgKph2o and Lgkpco2) depends on one of the outputs. The 2 interpolation tables transfor the output variable (temperature) in this two inputs. All components works fine independtly (first "model", the one on the top), but if i link the exit of both interpolation tables mapleSim say it cant solve a lot of variables.


I need to get inverse kinematics model of a double inverted pendulum. I got a model but it gives error when I run. It seems to me that the inverse kinematics model is not quite right. If you are able to help me, I will be very pleased.DoublePendulumI.msim 

Thanks for your help....










I have to design a wheeled mobile robot for my bachelor-thesis. the robot should be controlled in Simulink. Therefore, I have to use the Simulink Component Block Generator. Outputs are: yaw angle/rate, absolute position in x/z and its derivatives, wheel angle and its derivative,steering angle. Inputs are one torque for steering and one torque for actuatuating for each wheel. -->6 torques (3 wheels). When I click on the "Generate and Compile...


How can we re-initialize a multi-body system, for example a three link pendulum, based on measurements obtained from various sensors? Can we generate a modelica custom component which has inputs from various sensors and the output is the re-initialized states for the multi-body system?

Thanks for your help....


I have a simulation file consisting of a number of modelica custom componets and maple custom components. I initially generated Random Data with mean 1 and standard deviation 0.5. Constructed all the blocks and combined with a multibody system, it worked fine. However, when I generated Random data with zero mean, then I have this error/problem "Simulation Problem: maximum number of event iterations reached (100) at 1.85000".

I used a couple of pre() function with clock=sample(0,0.01...

What do these parameters of Clutch mean,phi_nominal,w_small,k_locked?

And, how can I use them?

Anyone can tell me the detail?

Thank you.

Hi all,

I want to compare two signals where intersections between the two signals represent the instant of command (like boolean pulse) of a thyristor. The two signals are volatges and command of thyristor is boolean. A conversion of voltage to boolean signal should also done, I think ?

Thanks in advance

See image below.

dear sir, I want to use maplesim to import the modelica model of truetime network, but failed. the model is writen in modelica 2, is there any way to sovle this problem?
