when run example below

got error in linear_string and linear_string2

prototype must be a structured record type or a record, but received squeezed

There is a problem with the modelica code for custom component named CorneringForce
Regenerate or delete this component to correct this porblem....

........Matrix2Euler

i click the web said USD99

but after click into it, academic version is USD1,555

there are commercial version, academic version , what are difference?

i see that there are self balance robot and humanoid walk robot

what are the specification of size, length of components are they?

if simulate robot hand which has a string make a tension to grip object

what kind of string is it? where can buy robots components which fit the simulations it do?

will maplesoft cooperate with 3D printer to fit the reality of robots?

Hello,

I have just updated maplesim to the last version (maplesim2015).

On the multibody examples of the maplesim2015 library, I didn't have any problems.

However, when i try to launch a simulation on a model i have made with a previous version (which worked before I use maplesim2015), i meet this problem :

May you help me to make the troubleshooting ? For the moment, I didn't manage to locate the error.

Do you have some ideas about this mistake ?

Thanks a lot for your help.

Does anyone know how to achieve the state transition of a prismatic joint between active and passive in MapleSim? Recently, I want to realize such a state transition of a prismatic joint. Specifically, during a simulation, the joint can either be motion-actuated or passive according to some conditions. Actually, I tried to use SimMecahnics, but I failed. Hope anyone can give me some constructive suggestions. Many thanks!

Hi,

 

Is there a way to export all of the equations (from MapleSim) including the casual equations? I used Multibody Analysis template and Equations template but it only exports the acausal equations.

 

Your help is really appreciated.

Hi all,

How to build an uneven ground by MapleSim?

I want simulation a car runnung on this uneven ground.

Is there any method , proposal , orientation, or any thing can help me

 

Thank you

Hi all,

 

I met a problem while using the MapleSim7.

When I increase the plot points (which can be modeified in the setting tab) to get more accurate solution,

MapleSim does not show the simulation results (ex. graph) even though the simulation has finished.

MapleSim message only says "Done Simulating", but does not show the results.

 

When I set plot points "10000", I could obtain the results. However when I set "30000" for plot points, 

I couldn't get results.

 

What is the problem and how can I obtain the results with many number of plot points?

 

Hi, I build my simulation system in MapleSim, using the module 'Stepper Permanent Magnet' like this

 

But when I run this system, I get the followiing error:

System is underdetermined

 

When I delete the part about 'Stepper Permanent Magnet', the system runs well.

How to solve this problem? How to use 'Stepper Permanent Magnet'?

The Help file of MapleSim cannot proviod such help information.

Thank you.

 

 

 

 

Hello,

 

I want to simulating a mulitibody system, similar circular motion.

schematic diagram:

 

result:

 

Why the ball cannot keep on the circle?

Thanks

Hello, 

is there a way I can use data (variables) from Maple environment in the Maplesim environment. 

I have a scirpt in maple that generates the robots joints angles and need to use them in the 3D robot built in maplesim. I know I can export/Import data, but this sounds redundant. Is there a way to simply use an input block as a source of the data in maplesim and have the variable name generated in maple used int. Similar to what Matlab/Simulink does.. 

 

 

thanks.

hello

i have some problem when iuse the digital libray with the delay components:

i have this error: delay variable not found in dependent variable list, [`Main.TransportDelay1.x`(T)]

it seems that the delay function in the modelica language is not well treated in MapleSim . At this level:

 

equation
    y = if 0 < delayTime then if delayTime <= time then x_delayed else y0 else pre(x);
    x_delayed = integer(delay(x, delayTime));
end Modelica.Electrical.Digital.Delay.TransportDelay;

 

Thank you for your help.

 

 

Maplesim 7.0(1) installer looks for Maple 18 installation.  Will Maplesim work with Maple 2015?

If not, what is the expected date of making both products compatible?

Hi! I'm having trouble with the MapleSim "Equation Extraction" template. I have an extremely simple dynamics scenario with RigidBody at a particular position in a world; when the simulation starts, the body should simply start fallin with a constant acceleration, and I'm looking to extract kinematic equations for this situation.

However, the problem I have with the extracted equations is that they contain some rotational dependent terms that I wish to avoid - a lot of sines and cosines with arguments that I actually cannot match up to any variables in the model, or when I enable quaternion representation, terms like this:

What I don't understand is what exactly these rotation terms represent. The object should be falling straight downwards, and gravitation should be applied straight downwards, and when I start the simulation it does run through, also indicating that there should be no unbound variables. I'm not sure exactly what parameters in the Modelica model do they correspond to? I did not find any such angles in the object settings. And can I ask MapleSim to generate equations without these unbound rotation variables?

Hi! I'm trying to use MapleSim 7 to simulate some very simple physical situations, however after great many hours spent at this, I'm still unable to convince MapleSim to load and run even the simplest Modelica models, like:

model Main
  Modelica.Mechanics.MultiBody.Parts.Body o(r_CM = zeros(3));
  inner .Modelica.Mechanics.MultiBody.World world;
equation
  o.frame_b.f = {0,-9.8,0};
end Main;

It will report that o and world are "unknowns" and apparently does not recongize Modelica.Mechanics.MultiBody.Parts.Body nor Modelica.Mechanics.MultiBody.World. Do I need to do some extra steps to import extra libraries or enable some non-default components?  I went through various YouTube and other tutorials and didn't find a mention of anything.

When I look at some examples, often they refer to things like Maplesoft.Multibody.World - but these are proprietary Maple packages, and I need my code to use standard Modelica. Does this mean that MapleSim cannot run generic Modelica code like this?

I also tried running e.g. https://github.com/xogeny/HarmonicMotion and some other examples, with absolutely no success either. I'm quite confused because MapleSim has a lot of advertising about Modelica support... :-(
