I am trying to (again) extract the equations of the systems which have been done by me, but the equation extraction gave me wrong results.

 

For example;

The DC motor and the inverted pendulum equation must be 3. (third) order and only a differential equation.

The pneumatic motor and the inverted pendulum must be a differential equation (any order).

Also the hydraulic motor and the inverted pendulum must be a differential equation (any order).

 

I tried to use "isolate" command but it did not work for me in this case. How can I get the differential equations of the systems ?

 

I have added the MapleSim simulations and the differential equations that I had.

 

Please help me for this problem chain.

I need help for two exercise. In the first I have in the secondary circuit nothing, in the second exercise un inductor.thanksinduzione_fra_due_circuiti.msim



 

Thanks to Mr. Joe Riel, my previous problem is the port's name and the input signal's name was the same name was solved. It worked well in the new model but when I try to do exactly the same thing in my current model, the custom component can't be generated even if the "Check dimension" button shown that "no issues found". 

This time error is:
(in SetComponent) flattening error: Errors: Input length = 1
Error in Component btnGenComponent with the caption "Generate MapleSim Component"

Does anyone know from what this error "Input length = 1" happens? 

I am very appreciated for your help.

Hi everyone, I need to use the integral calculation in MapleSim but there is no MapleSim Block to do it. So I create a Custom Component and using the integral calculation from Maple, the expression of the equation was done. But when I click Dimension analysis button, one error popped out as the photo. Have anyone got the same error before? How should I do to solve it? Thank you very much.

I have training video that shows the visualization window "docked" below the main window.   Can this work space arrangement be done in sim2017 ??  

Also I push the anchor button and nothing seems to happen 

hi

by passing all steps to install Maplesim 2017.3 i confort the error "The system cannot find the file specidied" when i want to open it. what shoud i do?

I have modeled a 3D flexible manipulator in Maplesim. I intend to measure the torsional strain of the flexible beams. How can I do this??

I have recently reinstalled the MapleSim 6.4 but the probe windows do not appeaar anymore.

The image below shows that there are 3 probes (none are disabled) and when I run the simulation nothing happens.,

please help me on check my schmitt2.msim schmitt's trigger 

I have an excel macro file (enable macro or save as macro and run) in which the colour of cells keep changing by a macro named macro2.

Can we achieve it in maple or maple sim?

Any one please suggest a way for me to try out.

I dragged into model space prismatic FixedFrame and RigidBody components and prismatic joint along y axis. I also set mass m = 1 kg. The manual says set K_S = K_S and K_K_d in inspector parameter setting. It did not work out. So i set values 12 and 0.1 for K_S and K_d. I sreated subsystem sub of rigidBody and followed the following instructions,

Quote" PrismaticJoint.PlacethePrismaticjointandRigidBodyinasubsystemcalledsub.Thisallowsthe EquationTemplatetogenerateequationsspecificallyfortheselectedsubsystem.

After this i wanted to modify the equations. I could not. The same equation is reassigned.

Parameter and variable rows - are as shown in manual, but a blank row not available for user's use. But how do i get the variable x(t) there and rename it?

Thanks for an example of this chapter with an application of its use., if available with anyone?

Hi, i don't know what happened but every time that I run the simulation appears this: 

invalid input: Multibody:-GetMultibodyData expects its 4th argument, lsProbes, to be of type list(list), but received registerMultibodyVariable

If anyone can solve this problem, I am going to be very grateful. Thanks

Dear All,

This is probably an easy issue to solve.

I have imported an .xls file using the 1D lookup table.

I need the signal to be executed for 4 seconds which is also how long my simulation duration is.

So I set the Ramp height and rise time to 4s. For some reason when I display the signal using a probe it gives me the constant value of the first row of my Excel sheet. I need help to solve this! I have provided some visuals below.

Thank you for your time!

how to design antenna with maple i am looking for designing patch antenna using graphene 

Hello everyone,

For some reason, the rising edge block is not working how it is supposed to.

The component decription is as follows: "

The Rising Edge component triggers a Boolean expression, true, in the output, y, when a rising edge is detected at the input, u.

I am applying a step signal. (red waveform)

and this is the probe's measurement:

Why is it not detecting the rising edge?

Thanks,

John.
