I am a beginner of MapleSim. I study the MapleSim User Guide. I follow the Tutor 8:Modeling Hydraulic System. But the following issue occurs, as shown in the picture. I bet I follow the guide carefully.

Also, I find that if I open the User's Guide example,Chapter 6, Analysis of Simple Hydraulic System Network, which is the standard example,I simulate it and it works well. But if I delete the probe, and attach a probe at the same place , selecting same values to measure, and simulate again, it failed, giving the same error description. I need your help,please.

Application of MapleSim in Science and Engineering: a simulationbased approach

In this research work I show the methods of embedded components together with modeling and simulation carried out with Maple and MapleSim for the main areas of science and engineering (mathematics, physics, civil, mechanical etc); These two latest scientific softwares belonging to the company Maplesoft. Designed to be generated and used by teachers of education, as well as by university teachers and engineers; the results are highly optimal since the times saved in calculations are invested in analyzes and interpretations; among other benefits; in this way we can use our applications in the cloud since web technology supports Maple code with procedural and component syntax.

## An Adaptive On-Line Identification Method

In order to estimate parameters of permanent magnet synchronous motor (PMSM) on-line and real-time, an adaptive on-line identification method for motor parameters is proposed. Resistance, inductance and PM flux of PMSM are achieved at the same time in the presented model. By means of Popov’s hyper-stability theory, the model of parameter identification is built in the rotor reference frame. And, PMSM d, q-axis voltage, current and their errors are used to obtain the adaptive laws of parameters. Popov’s hyper-stability theory guarantees stability of the system and convergence of the estimated parameters under certain conditions. The simulation and experimental results illustrate the validity and efficiency of the proposed method.

Maple 2019.2 includes corrections and improvements to a variety of areas in the product, including a new “Go to page ____” option in print preview (that am personally quite pleased about), sections are expanded by default when printing or exporting, a fix to a problem using non-executable math with text in document mode that sometimes made it impossible to advance to a new line using Enter, improvements to VectorCalculus, select, abs and other math functions, support for macOS Catalina, and more.  We recommend that all Maple 2019 users install these updates.

This update is available through Tools>Check for Updates in Maple, and is also available from our website on the Maple 2019.2 download page, where you can also find more details.

## Intermediate Axis Theorem in MapleSim using Multib...

Has anyone made a physical model to recreate the Intermediate Axis Theorem? This is also known as the Tennis Racket Theorem, or the Dzhanibekov Effect. The science Youtuber Veritasium has made a recent videos on this this topic.

I'm interested in recreating the spinning and random flipping of the "T" tool using Multibody as seen in the above video.

## Pole simulation with tensions in MapleSim

Application developed using Maple and MapleSim. You can observe the vector analysis using Maple and the simulation using MapleSim. Also included a video of the result. It is a simple structure. A pole fastened by two cables and a force applied to the top. The results are to calculate tensions one and two. Consider the mass of each rope. In spanish.

## Problem of modeling Schatz mechanism in MapleSim ...

Hello,

I'm working in MapleSim to model a mechanism called Schatz which has a six-Revolut, known whit TURBULA name.
I modeled the mechanism in CREO to have a CAD part to use in maplesim.
everything is okay when I run the simulation without a speed constant. as shown in the picture above.
when I add a speed source, MapleSim finds an error (Internal error occurred during the simulation).

## Component in Maplesim user library no onger visibl...

I created a user library and added a component that I had created from a shared subsystem and this worked fine.

I edited the component in the library to add some additional functionality and saved it.  I then had to reload the library in Maplesim but now I get this error everytime I try to run the simulation:

Cannot resolve `ControlLogix.PIDE` in model `Main`; there is no `ControlLogix` visible

Yet I dragged and dropped the component PIDE from the ControlLogix library.

Can anyone help me to resolve this?

Thanks

We are currently in the process of updating the support FAQs at https://faq.maplesoft.com. We’ve been working on updating the existing content for clarity, and have added several new articles already.

The majority of our FAQs are from questions people ask us in Technical Support by support request form, but we’d also like to like to add content from other sources.

Since we have such a great community here at MaplePrimes, we wanted to reach out and ask if there are any articles or questions that you'd like to see added to our FAQ.

We look forward to hearing your feedback!

## has anyone tried to use Peter Fritzone's book with...

has anyone tried to use Peter Fritzone's book with maplesim helloworld modelica??

The simple approach from Peter (creating a custom modelica component) is to getting started by running a simple simulation where x_dot(t) = - a*x,  where the normal form is x(t) = x^-a for logarithmic type decay.

plot of x(t) should be a decay curve.

Maple Code

SimData := A:-Simulate(outputs = x, returntype = datapoints, tf = 2);

Error, invalid input: Simulate expects value for keyword parameter [outputs, output] to be of type {list(algebraic), list(anyfunc(identical(t)))}, but received x

## can maple sim simulate a robot arm and hand catch ...

can maplesim simulate a robot arm and hand catch a throwing ball and picking objects?

can maplesim simulate a balancing a robot legs?

will these simulation require complex formula to draw the robots arm and hand and maintain the joints stick together during motions?

can maplesim output the specification to autodesk for 3D print parts?

i can not see the price in maple official site from Hong Kong area.

## How do I reference a Custom Port when I create a C...

I have created a custom port in my MapleSim file and when I try to add the port to a Custom Component I keep getting an error that the connector cannot be found.

The custom port appears in the components pane of my MapleSim model.

I am guessing that I am missing something to fully qualify the port name.
