Whenever I have 2 instances of the rotational move block in a model, mserver.exe crashes when I try to run the simulation. Why is this?

I want to define the inertia matrix of a body within a subsystem as a subsystem parameter. I can define constants (like mass), but I cant define the 3x3 inertia matrix. It looks like MapleSim returns a dimensional error when I try to simulate the model. How can I assign the inertia of the rigid body to a parameter?

I am trying to create a Simulink component block from a MapleSim subsystem. I have one input to the subsystem, and the Specified Inputs and Outputs section of the MapleSim Connector worksheet also shows that the subsystem has one input. However, When I export the model to Simulink, there is no input port, just one output. How can I fix this?

Current I need model a mechanical system with kinematic loop. In Maplesim4 the calculation speed is too slow. I need to use this model in HILS. How to solve this problem? I check the 'four bar' example, It's too slow(simulation 1 second, 40second is needed, Intel xeon 3GHz,2cpu) Anyone who can help me? Thanks! Wander

Who knows how to model a brushless dc motor?  Can I use a synchronous machine and some circuits? Brushless dc motors do require rotor position information in order to select the appropriate commutation angle. Using three Hall sensors? But how to model a hall sensor or something which can specify the rotor's position and send out a signal? I am looking forward to your answer. If you have some experiences of modeling a double closed-loop dc machine using maplesim, please tell me too.

Hello

I Wanted To Model a Ball Screw in MapleSim4, I should  Imply a force to the base of the ball screw while the nut is attached to a fix pint and I expect the shaft of the ball screw rotates. I would be so thankful If any one tell me an idea how to model it to use at Maplesim4 for as I could not find any component for ball screw on MapleSim.

Looking forward to hearing from you

"User-selection of 

With MapleSim it is possible to simulate electronic components. But it is not possible to build a model from an existing electric layout. This means, I have to copy for each electric part the data from the datasheet by hand and to connect them. For simple layout this is time consuming, for complex layouts it is impossible.

There are Layout software like EAGLE ( http://www.cadsoftusa.com/index.htm.en ) to build up complex electric circits, with the data and geometry...

Hi all,

i would like to modify plot curves with different coloration in the optimization template coming from a maplesim document.

in the startup code of the maple 13 template i tried  to modify code in order to get the plot form with my custom design every time i open it, without the necessity to change again settings after each simulation.

The problem is that in the help section i don't find any examples about changing different expression curve propriety in a list of list and don't understand how to proceed.

 

I upped an example to show what i want. I need to connect the blue and yellow joint with a rigid body frame. The length of this frame should MapleSim derive from the initial position of this arrangement by itself (Spherical Joint S1 and Revolute R3 have strictly enforced initial conditions, yellow joint has a fixed position). Is there such a feature like inserting a frame between two given points in MSim4 ?

Is there a way to undock the window with the 3D visualization. (as a new window)

If I change the size of the window, the size of the visualization window is not updated.

How do I change the dimension of the Visualization?

Imagine a simple pendulum

:

In the construction mode it looks like this:

But if I change the length of the RBF from 1 meter to 1cm it looks like this:

hello,everyone,who can introduce the use of "free motion" component?

Hi everybody out there! Here is a perhaps a newbe question! Is it possible in MapleSim to save a plot of, say x(t) with respect to t, as a table of values in a file? Let's say I have a 2D plot of x(t) with respect to t, and I want to save the table of values (t,x(t)) in a file where t ranges in t1, t2, ..., tn. Such a file is supposed to be used by external applications. Is this possible in MapleSim? Thanks for your hints. Sette

Hello,

I am wrting my thesis which is on some MapleSim models. In Ref I introduce MapleSim, I wanna know if MapleSim has Document Object Identifier (DOI) number or name that I can refer to.

Thanks so much,

Bye
