Hello,

In my model, in order to better follow a analytical study, i would like to make some calculations with my paramters.

For example, I have defined :

xa=1

ya=2

R=sqrt(xa²+ya²)

I would define R in the parameters area so as to use it for some definitions in the definition of body (i use especially maplesim for multibody systems.)

How is it possible to define parameters thanks to relations ?

Hello all,

When I try to do this example, in the multibody analysis, http://www.maplesoft.com/products/maplesim/ModelGallery/detail.aspx?id=137

Thats already written :

 

but when I enter theses formulas(mModel & MB), that write instead of the example:

"Analyzing system..."
"Performing constraint analysis..."
"The system has 2 degree(s) of freedom. It is modeled using 2

generalized coordinate(s) coupled by 0 algebraic constraint(s\

And I have no result if i do vPosCons := MB:-GetPosCons(); . What am I doing wrong?

Thank you

Hello,

I would like to open a modelica model with MapleSIM. When I do "import modelica", I received the error message : "import failed : no library found".

I believed the modelica library was already installed on maplesim but may be not. Do I need to install modelica library ? and if yes, how ?

More generally speaking, how can I do to open a modelica model on maplesim?

Thank you for your help.

I have some data for a model in MapleSim that I would like to use a time look up table with.  I've found that the two options for interpolation are linear and 1st derivative, but the data was intended to be interpretted as piecewise constant.  Is there any way to acheive this option in MapleSim?

Hi

I tried to import the modelica library Buildings1.6 from the modelica website and get always the error "Nothing found in the modelica library". 

Is it possible to import modelica libraries? 

Thank you very much

Does MapleSim 6 cover temperature dependent fluid media? In the modelica standard library (MSL), there is for example a medium model for T-dependent properties, defined by tables or polynomials (Modelica.Media.Incompressible).

 

Is it included in MapleSim 6 or can be somehow modelled?

 

Thanks!

Maplesoft regularly hosts live webinars on a variety of topics. Below you will find details on some upcoming webinars we think may be of interest to the MaplePrimes community.  For the complete list of upcoming webinars, visit our website.

 

Hollywood Math (with more new examples!)

Over its storied and intriguing history, Hollywood has entertained us with many mathematical moments in film. John Nash in “A Beautiful Mind,” the brilliant janitor in “Good Will Hunting,” the number theory genius in “Pi,” and even Abbott and Costello are just a few of the Hollywood “mathematicians” that come to mind.

Although the widespread presentation of mathematics on the silver screen is not always entirely accurate, it does serve as a great introduction to the study of mathematics in general. During this webinar Maplesoft will present a number of examples of mathematics in film. See relevant, exciting examples that you can use to engage your students.At the end of the webinar you’ll be given an opportunity to download an application containing all of the Hollywood examples that we demonstrate.

Applications of Symbolic Computation in Control Design

You may already use Maple and/or MapleSim within your organization to solve various problems, but did you know that they have capabilities for control design as well? In one of our upcoming featured webinars for this month, we will explore the Control Design toolbox including the ability to extract symbolic equations of plant models, perform symbolic linearization, design symbolic controllers, and generate very fast code for HIL testing.

The following examples will be demonstrated:

• PID Control

• LQR, Kalman filter design

• Gain scheduling

• Feedback linearization

Updates are now available for both Maple 18 and MapleSim 6.4.

Maple 18.01 includes a variety of enhancements, including:

  • Significantly enhanced  efficiency for many  numerical linear algebra computations
  • New keyboard shortcuts for “Execute All” ([Ctrl or Cmd]+[Shift]+[Enter]) and for entering slideshow mode ([F11] or [Cmd]+[F11])
  • Improved export of 2-D plots
  • PDF export improvements for documents that include  code edit regions
  • Enhancements to the limit command

 To get this update, you can use Tools>Check for Updates from within Maple, or visit Maple 18.01 Downloads.

MapleSim 6.4.01 includes:

  • Improvements to the templates for creating custom components using discrete state space and discrete transfer function descriptions
  • Improved handling of variable names that include both symbols and numbers
  • UTF-8 filename support
  • Improved backwards compatibility of the Parameter Inspector with older models

 

In MapleSim, use  Help>Check for Updates or visit MapleSim 6.4.01 Update. For best performance, we recommend that you run MapleSim 6.4.01 with Maple 18.01.

Hi everybody.

 

There are several weeks I'm on a school project and for it we need a Maplesim Simulation. It contains a sine voltage (source), a diode bridge (simplify), a condenser and a resistor. The problem is : when I want to simulate it, an error message appears : System is undetermined. I dopn't understand why I've this and from where's the problem...

 

If you could help me asap, it will be very very nice.

 

Have a nice day.

Recently I started to learn to use maplesim. I wanted to set up a feedback system which is used to control the speed of DC motor. I don't know how to build it. Please give me some advice. I really appreciate your help.

Hi

I want to create a linearied model for a single or multi degree of freedom vibration system by MapleSim. i faced a lot of problem such as causalize ports, i search the user manual but i didn't find it useful. i attach a very simply one degree of freedom vibration system. i wondering if every one create a linearized model for it. my final goal is governing the equation and determine the natural frequency with nyquist plots. i have mapleSim 6.2 and Maple 17. Thanks

Hi

As i asked at title; i want to determine natural frequency of a single or multi degree of freedom vibration system using MapleSim. but i can't and i don't know how i can do it. can every one help me plz?؟؟؟

MapleSim 6.4 includes more powerful tools for creating custom components, performance enhancements, and enhancements to the model generators for Simulink® and FMI. 

We have also made important updates to the MapleSim Control Design Toolbox. This toolbox now offers a more complete set of algorithms for PID control, new commands for computing closed-loop transfer functions, and numerous improvements to existing commands. These enhancements allow engineers to design a greater variety of controllers and controller-observer systems while taking advantage of the greater flexibility and analysis options available through the use of symbolic parameters. 

See What’s New in MapleSim 6.4 and What’s New in the MapleSim Control Design Toolbox for details.

After simulate the model of MapleSim, I can only know the curve of where I need to know about. I need the specific parameter(each point value), like a piece of sheet. How I can put it of in an Excel of Word?

Hi

Is MapleSim 6.1 fully Modelica 3.1 compliant? If not, which features does it miss for the moment?

Lookup tables? (modelica ones, not maplesim's)

Thank you very much
