## DC Motor example - How do i get output in plot...

I followed the basic example RLS circuit first. It worked out well for R = 24 ohms, L = 160 mHand C = 200 microF. Signal is step input h = 1 and  t0 =  0.1 s. Simulation td = 0.5 s

When I extended it for DC motor, the output for torque (tou) and speed (w) not plotted for h = 1  t0 =  1s and simulation td = 5 s for the same parameters as above the output required (shown in manual) is not coming. Is it because default values shown were different? Then how do i change? I am enclosing the file for view and help.

## Constraints on Revolute Joints...

Hello,

I have an industrial robot model and I need to define constraints for the revolute joints. For example, R2 joint is only allowed to move between -165 to 165 degrees. Could you please tell me how I can impose these constraints?

Thank you.

## How do I solve this problem in MapleSim?...

Hi, i don't know what happened but every time that I run the simulation appears this:

 invalid input: Multibody:-GetMultibodyData expects its 4th argument, lsProbes, to be of type list(list), but received registerMultibodyVariable If anyone can solve this problem, I am going to be very grateful. Thanks Main

Dear All,

This is probably an easy issue to solve.

I have imported an .xls file using the 1D lookup table.

I need the signal to be executed for 4 seconds which is also how long my simulation duration is.

So I set the Ramp height and rise time to 4s. For some reason when I display the signal using a probe it gives me the constant value of the first row of my Excel sheet. I need help to solve this! I have provided some visuals below.

Hi everybody,

Neither of these questions is vital but answers will be greatly appreciated

-------------------------------------------------------------------------------------------------
Question 1 :
Is it possible to manage programatically the character fonts in a printf command ?
(for instance to print some piece of text in bold font ... without selecting it and clicking the bold B of the toolbar)

-------------------------------------------------------------------------------------------------
Question 2 :

In order to have a nice render, I use to create my own format for printf command. For instance, when I have to “printf” some text I usually compute its length L and my “printf” format constructor contains a command  like  MyFormat := cat(“%”, L, “a”)

Unfortunately the length(…) command seems to be sensitive to accented characters :
For people not familiar with french, "dégénéré"  (note the acute accents) means "degenerate".
length(“dégénéré”) returns 12
length(“degenere”) returns 8
… which of course leads to a very inelegant render, which is all I wanted to avoid

Why does “length” behave this way ?
Is it possible to bypass this annoyance while ensuring “dégénéré” has length 8 ?

Hello,

I know that it is possible to conduct the dynamics of multibody systems with MapleSim. But, is it possible to conduct only the kinematics ? Would it be possible to share a example where only the kinematics is conducted with MapleSim?

## Inspiring Young People to be Science and Technology...

Maplesoft aims to promote innovation in science, technology, engineering and math (STEM) in high school students by partnering with various organizations, and sponsoring initiatives in education, research and innovation. Every year, Maplesoft commits time, funds and people to enhance the quality of math-based learning and discovery and to encourage high school students to strengthen their math skills.

One such organization we partner with is The Perimeter Institute, a leading centre for scientific research, training and educational outreach in foundational theoretical physics.  Maplesoft currently serves as its Educational Outreach Champion, supporting various initiatives that promote math learning and exploration. Perhaps the most popular of its student outreach program is the annual International Summer School for Young Physicists (ISSYP), a two-week camp that brings together 40 exceptional students from high schools across the globe.  Each year students receive a complimentary copy of Maple, and use the product to practice and strengthen their math skills.  The ISSYP program also uses Möbius, the comprehensive online STEM courseware platform from Maplesoft, to offer preparatory course materials to students.  Completing lessons in Möbius aid in making the summer program a more productive and dynamic experience for the students.

International Summer School for Young Scientists at Perimeter Institute

Who Wants to Be a Mathematician is a competition organized by the American Mathematical Society (AMS) for high school students in North America. Maplesoft has been a sponsor of the contest for many years.  Maple T.A., the testing and assessment tool by Maplesoft, is used to administer the tests online, saving significant time and money for the organizers. When Maplesoft first introduced Maple T.A. to the contest, taking the competition from pen-and-paper tests to online tests, the number of contestants doubled, with about 2000 students participating in the contest. Maplesoft also donates prizes to the games in order to promote the use and love of math by high school students.  This year will be first time the competition moves international. Six students in the UK took the Round 2 qualifying test, with the use of Maple T.A., and qualified for the live, on-stage finals of the UK edition of the competition that took place at the 2017 Maths Fest in London. Maplesoft is also supporting the spread of the WWTBAM contest to Canada in 2017.

Maplesoft also sponsors two outreach initiatives in Texas A&M University.  The Summer Educational Enrichment (SEE) Math Program is a summer workshop attended by gifted middle school students. Students spend two weeks exploring ideas such as algebra, geometry, graph theory, and topology.  The University also conducts the Integral Bee every year, a math based contest for high school students.

In addition to the above key projects, throughout the year Maplesoft also sponsors and is associated with a number of other competitions, conferences, and educational initiatives. A few of these are listed below.

• The Connecticut Science & Engineering Fair is a yearly, statewide science and engineering fair open to all 7th through 12th grade students.  An important objective of their program is to attract young people to careers in science and engineering while developing skills essential to critical thinking.
• FIRST Robotics Competition is a high school robotics competition. Each year, teams of high school students and mentors work during a six-week period to build game-playing robots that weigh up to 120 pounds.

FIRSTRobotics Competition

• ScienceExpo Conference is a student-run event that engages students with STEM-related opportunities and workshops
• SWATposium is an annual robotics conference that brings together nearly 40 First Robotic Competition teams from both Canada and the United States for a day of guest speakers, workshops and social activities.

SWATposium

• FIRST LEGO League gives elementary and middle school students and their adult coaches the opportunity to work and create together to solve a common problem.

FIRST LEGO League at St. Luke's School in Waterloo

Maplesoft’s objective of these sponsorships is to support those who inspire and channel young minds to be STEM focussed. By engaging them in exciting contests and programs the hope is that they build science, engineering, and technology skills at a young age and grow to be innovators and technology leaders of tomorrow.

## How can I import the Modelica library from the Mod...

I have tried to do it by the following command "File/Modelica/Import Modelica Library" in MapleSim GUI. An error appears saying "Modelica is a reserved name".

I think you can also reproduce it by downloading the Modelica library from the following web site: "https://www.modelica.org/libraries". And then importing it in the usual way by openning the package.mo file at the root directory.

I think I am missing something here, so any advise/information/minimal commentary would be greatly appreciated.

Cheers, Ovle

## MapleSim: Custom Component - How can I find min be...

Hello everyone,

I am trying to create a custom component to find the minimum between 3 values.

I know that in Maple it is done by:

l := [5, 2, 3];
min(l[1], l[2], l[3]);

However I could not do the same with a custom component. I provided a screenshot below, where h(1), h(2), and h(3) are my input values and min(h1,h2,h3) is my output.

## MapleSim - Rising Edge Block is not working!...

Hello everyone,

For some reason, the rising edge block is not working how it is supposed to.

The component decription is as follows: "

The Rising Edge component triggers a Boolean expression, true, in the output, y, when a rising edge is detected at the input, u.

I am applying a step signal. (red waveform)

and this is the probe's measurement:

Why is it not detecting the rising edge?

Thanks,

John.
