Hello,

In my mechanism, I use absolute coordinates.

For the rotation (namely the initial angles/ angular velocites), I didn't see the difference between Inboard and Euler.

It seems to me that in the two cases, the initial angles are defined with regard to the inertial frame and for both, different kind of rotations can be defined.

Have you some ideas on these two options ?

Thank you for your help.

Hello,

I don't why I can no longer see my multibody model in the 3D construction mode.

I probably should desactive something.

I would like to observe my system with the kinematic constraints not enforced.

The idea is that my model is computing but the computation is very long. I should have done a mistake in my initial conditions.

Do you have an idea of what to do to reactivate/ show again the 3d contruction mode ?

Thank you for your help.

The following error occurred when I simulate a build-in model, anyone could help me to solve this problem? Thanks first

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 need to model some spherical joints with damping.

Apparently, contrary to revolute joints, it seems that it is not possible to add damping in spherical joints. Indeed, contrary to the revolute joint where there is an option to put spring or damping element, i don't find this option in the spherical joint. 

Do you have a idea to model spherical joints with damping (without changing the spherical joint)?

Thanks a lot for your help

Hello,

How to building a wall, I want to use the wall with something (ex:ball) make a elastic collision.

Thank you all.

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.

Hallo,

I am facing a problem with the c-code generation of maplesim models:

When I am trying to compile a multibody model that contains more than about 80 bodies I get an error "Error, (in GetCompiledProc) internal error: unable to find matching".

Using the code generation template it says "Error in Component cmdGenerateCode eith caption "Generate C code": (in DSN/Pantelides) internal error: unable to find matching"

 

Has anyone a solution to this?

 

Edit:

Model: Ref_Model.msim

It is a simple systems of masses connected by spring/dampers.

I am using MapleSim 7.01

The error message occurs when I try to simulate the model in maplesim, too:

Simulating...
Using the Mark II engine
Simplifying system with 600 equations
Simplification removed 0 equations. Remaining equations: 600
Generating simulation code
DAE index reduction
DSN/RunSimulation: internal error: unable to find matching
(in DSN/RunSimulation) internal error occurred during simulation
Simulation failed.

 

 

 

I make a new parameter in MapleSim, but I don't konw why it becomes to something as shown in the above figure.

In MapleSim environment, I can see these code, but I find that I cannot edit them.

Is there a method that I can edit these codes?

Thank you.

 

I want to make the model which moves along the specific direction (translational), So I used the "prismatic joint" to give the direction that I want to enforce. However, "Prismatic joint" only offers the direction along the "X", "Y", and "Z" axes though I want to give other direction.

 

Is there any way to give the specific direction (vector) to make my model move in that way ?

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.
