MapleSim 5 Questions and Posts MapleSim 5 Questions and Posts Feed

Does anyone know how to switch a joint between having a prescribed motion driver and acting as a passive joint? More specifically, I am building a bed of spring to serve as a model for haptic feedback on a Phantom Omni device. Therefore, I need to read the position of the device (which is not a problem) and then based on the position of the device calculate a force to feed back to the device.

Consider the simplified example below. In one situation I may need to give...

Hi,

Well, I'm trying to connect a translational spring to a revolute joint. But, I'm unable to do so. I'm new to MapleSim and I ain't a mechanical engineer either. I need you to help me a little. Anticipating a quick response!

Hi,

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...

Hi all,

I have a modelica custom componet which has inputs from angle/speed sensors and the output is a vector. I have an error "Attempted to retrieve property of unknown component". Can anyone see mistakes from the code below;

model basisFunction
    extends Maplesoft.Icons.CustomComponent;
    parameter Real bPen[sn*sn] "The normalized output for the basis function";
    parameter Integer sn=5 "The number of samples in each axist";

Hi All,

I am trying to apply a learning algorithm to a pendulum. The algorithm has Modelica custom components and also MapleSim custom components. I need to reinitialize the simulation  (i.e new initial states for the pendulum) without stopping the simulation. I think I have to use a Modelica custom component since there is a "if" condition and there is a function called "reinit()" in Modelica, but I am not sure how this works...

if you have...

Hi all,

I'm currently running a parameter space search via Maple scripting. The pseudo-code goes something like this:

fopen text file to write data to;

initialize parameters (variable) x, y, and z;

for x number of iterations

   A:-Simulate(model.msim, with [parameters]);

   Update parameters with new values;

   Write to text file;

end do;

fclose(text file)

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?

Hi all,

A while ago, I had asked a question relating to calling to an MapleSim .msim simulation within maple .mw worksheet. (Thank you Acer! :) I got it working but then another issue just popped up...The basic structure is as follows:

********************************************************************

A := MapleSim:-LinkModel('filename' = "TriplePendulum_WORKS_v2.msim")

for z from 1 to 50 do

     initialize_variables;

Hello,

I have created a MapleSim model including a few custom components. When I try to run the simulation, I receive the following error:

cannot resolve function `Main.'Typesetting:-mambiguous'`; there is no function `'Typesetting:-mambiguous'` visible in model `Main`

How do I know where the source of the error is?

Thank you,

Bonjour

Je n'arrive pas à faire fonctionner un montage simple.

J'ai un message d'erreur : (in dsolve/numeric/RunSimulation) unable to compile, please check your options by running with infolevel [ToExternal]:=1; simulation failed.

Que dois-je faire ?

Hi,

How can I model a ground pattern, like was done in the demos of the planetary rover (http://www.maplesoft.com/products/maplesim/demo/OrangWowMoment.aspx)?

I see in the block model of the planetary rover that there is a component called "ground pattern" and it is not connected to any of the other components of the model, and this component is also not part of any default libraries of Maplesim.

Hello,

I downloaded the Modelica_Fluid 1.0 Library from the Modelica website. When I try to import this library into MapleSim5 I get the following error:

Duplicate class definition found for Modelica_Fluid.Pipes.BaseClasses.WallFriction.Detailed.msim/UNKNOWN

I then click "ok" and the importing stops working with the last message being:

Querying Modelica classes...

Can anybody offer help with this?

Hi simulators

Is there an easy way to give a global time frame/limits for all plots: typically I need to simulate a few seconds to get rid of all my transients, and then I would like to zoom in on the effect of interest. Now I have only found out how to reset one by one each graph via the axis properties, I have a dozen graphs per simulation 4 variables to scan over ten points each, that makes a damn lot of graphs properties click to reset, results: I need 60 sec to...

MapleSim has been delivering unique advantages in physical modeling and system simulation for many years. Today we release the latest iteration: MapleSim 5. Looking back at some of the earlier versions of our software, it is hard to believe that this is the same product; from the user interface to the component libraries to the simulation engine, every part of the system has experienced a striking evolution.

Like its predecessors, MapleSim 5 is based on the Maple mathematical...
