1.For win 8, does there exist an arm version maple in future?

2.Will it possible to use gpu acceleration for symbolic computation in maple?

## Modeling a Double Pipe Heat Exchanger with MapleSi...

A prospective customer recently asked if we had a MapleSim model of a double pipe heat exchanger. Heat exchangers are a critical unit operation in the process industries, and accurate models are needed for process control studies.  I couldn't find an appropriate model so I decided to derive the dynamic equations, and implement them using MapleSim's custom component interface.  I'll outline my modeling strategy in this blog post.

Hello,

These days I thought a question:how to creat a variable delay?

As illustrated in Fig.1, if delay time T is constant, then the output is y(t)=u(t-T), so we can use a block named "Pade Delay" in maplesim to achieve our purpose.As shown in Fig.3.

If delay time is variable,namely,T(t), then the output is y(t...

## How to obtain the voltage of a circuit ?...

Hello,

I use maplesim to simulate a very simple circuit, and want to obtain voltage of a resistor, so I check the voltage of  Probe block, but get nothing. I upload my document.

## need help to determine the max of function...

Hello,

it's my first utilisation of MAPLE, and I want to determine the max of a function y(x). I have this differentiel equation with 2 variables :

a*diff(y(x),x,x) + b*(diff(y(x),x)-diff(z(x),x)) + c*diff(y(x),x) + d*y(x) + e*(y(x)-z(x))= 0;

I resolve it whith the function "dsolve", and now and I want to calculat the max of the function y(x).

can any body help me ??!!!

thanks

## Green Cars

My father’s first car when our family moved to North America was a 1970 Buick Skylark sedan, and the color was a majestic deep green. I was seven years old at the time and this was my first experience with a green car. It’s ironic that my life in North America started with a green car and has come full circle with green cars all over the place as far as my job is concerned. But of course, today’s green car is really about highly fuel efficient cars...

## How to use maplesim to generate several curves in ...

1map.msim

Hello,

I use maplesim to simulate a simple delay system,as the document illustrated,I set the delay values from 0 to 4*Pi/(3*sqrt(3)) . I want to use a single souce to drive four branches, and use "probe" block to generate a figure which contains four curves according to different delays. So I use  a block "4-port Demultiplexer" which selected from Signal Blocks\Routing\Demultiplexers,...

## Uncomprehendable Warning...

I am working on hybrid dynamical systems an encounter the warning: "dependencies in discrete equations cannot be ordered". What does this mean and should I care about it?

## Science Fiction Double Feature

Like many in the technology industry, I am a big fan of science fiction films and I’ve written in the past about how exciting it is for me to have a job where science fiction and reality literally meet. Over the past few months, several key projects from various Maple and MapleSim users caught my attention for various reasons and once again, I was forced to giggle publicly as the shear cool factor of these applications overcame my normal mature demeanor.

I am looking to use MapleSim in my MSEE Thesis project. I need to capture input from a hardware system, then use that data to drive a model in MapleSim, using MapleSim as a 3D kinematic model.

I have been using Python for most of my work so far, so that would be a preferred language, but I am also comfortable with C++, it just takes longer.

I am brand new to MapleSim (I have not even received it yet), so if there are some documents you could point me to, then that would be just great!

## Generating an exe file from maplesim model...

I would like to know if it´s possible to generate a standalone .exe program based on Maplesim models, to be used out of maplesim and integrated with other tools i have.

I can use compilation in maplesim, but this just speed up the simulation, without giving to me a compiled external code.

I´m having to export maplesim modelica model to openmodelica environment, and generate an exe code there. the input and output parameters are transformed into text...

A new release of MapleSim is now available.

• Enhanced Modelica support, including the ability to access new collections of components using the Modelica import feature

• Increased speed and modeling capabilities for continuous systems with discrete events. The enhanced engine handles a far greater class of these systems than earlier versions, and shows significant...

## How do I solve the fourier series of the curve gen...

I built the shock model in MapleSim

then I got the response accleration

For this curve, I want to solve its fourier series in Maple.

Do it work?
