with this simple circuit i found a wrong simulation result : look at the probe 3 value. someone could help me please ?

The same error i found in this circuit (binary adder)

Hello,

Concerning the 3D visualization of my multibody systems, in the visualization windows, i can see both :- the display of geomtry of the elements which has been defined as simple forms (as cylindrical geometry)- the display of the geometry of the elements where the display of the geometry has been defined with CAD.

However, concerning the 3D animation, i have only see the components where the display of the geometry is defined as simple forms (as cylindrical geometry).

Have you some ideas why I can not see the elements which has been defined with CAD ?

For your information, the CAD geometries have been defined with STL files and, in the CAD geometry component, I let the box "Transparent" empty.

Thank you for your help

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.

On my multibody model, I meet a mistake during the simulation which is the following :"Constraint projection failure at 10s".

1) Do you have a idea on this error message so as to correct the settings for the simulation?

2) I would like to know more about the projection method. If, I'm not wrong, there is not a lot of documentation about the projection method used in Maplesim.

a) Does someone have some references (scientific papers) which present the theory used for the projection method in Maplesim?

b) In ths sense, I would be very interesting about learning the theory of the projection method in order to be able to tune correctly the following options linked to the projection method :

- Projection Iterations- Projection Tolerance- Event Projection- Event Iterations- Event Hysteresis

Is it possible to define the orientation of a body with a matrix transformation ?

I have seen this option for the fixed frame but not for the rigid bodies.

I would like to define the rigid bodies thanks to transformation matrix so as to make some checking.

Thank you for your help.

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 ?

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 ?

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

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.

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

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