I am trying to extract the underlying equation for a simple operational amplifier circuit in MapleSim 5.  The same process that I had used earlier for a simple resistor circuit (without opamp) worked fine and yielded equations.  However, when I try to do the same thing with an opamp (configured to do a simple amplification of an input voltage) I get a blank "View Core Equations" box in the Equation Extraction attachment. 

Thanks!

The input signal is given above. I don't kown how to get ti in MapleSim whether use custom component or not. Is there anybody can do me a favor. Thank you very much.

Hi,

Well, I'm trying to connect a translational spring to a revolute joint. But, I'm unable to do so. I'm new to MapleSim and I ain't a mechanical engineer either. I need you to help me a little. Anticipating a quick response!

Hi all,

1.msim

I want to compare two signals with relational block in Maplesim, i.e. greater or equal

The output signal should be a pulsed signal which represents the intervals where one signal is greater or equal to the second signal

How to do this

Thanks

Hi!

My problem is that MapleSim refuses to use my interpolation table, and the simulation stops, because it says the first column is not in ascending order. Seems easy to solve, but it is not! The column IS in ascending order, I even arranged it several times in Excel. I can't figure out what is the problem.

If someone has time, I attached the interpolation table.

Best regards; e6.xlsx

Hmmm, I'm not sure if this possible but worth asking...and maybe useful for creating custom loop simulations:

I have a trajectory profile (via 1D Lookup Table in MapleSim) whose duration is for 10 seconds.

Is it possible to create a simulation with an end time greater than 10 seconds and have the 1D Lookup Table repeat its profile after it ends:

Example: Simulation end time = 20second. Thereby having the Lookup Table execute twice.

Suggestions on approach? Thanks.

Hi All,

I am trying to apply a learning algorithm to a pendulum. The algorithm has Modelica custom components and also MapleSim custom components. I need to reinitialize the simulation  (i.e new initial states for the pendulum) without stopping the simulation. I think I have to use a Modelica custom component since there is a "if" condition and there is a function called "reinit()" in Modelica, but I am not sure how this works...

if you have...

Hi

I am working with mapleSim in two different computers, one in my school and another that is mine. I am using dropbox to keep the mapleSim documents and the costum component that i am creating synchronized in both PC´s. But i have noticed that mapleSim store the file that i attacht in another folder, so when i change the components equations in one document, on the other PC there are no changes. Is it possible to change the folder where the...

Hi All,

I want to create a MapleSim Custom Component which has a vector input and the output is a matrix. In this case how can I define the system (Dynamic system sys:=DynamicSystems[?])? Hence, how can I assign these input/output to component ports?

Thanks

Hi all,

I have some problems to model a DC-AC converter with transistor. Can some one take a look in my maplesim file and help to correct it

Thanks

hi

I am a mechanical engineer student and i am trying to learn mapleSim, but i am having some dificulties.
I am first trying to model an heat exchanger from a domestic water heater. I have found on maples website a costum component and i am trying to do a similar one to start.
The component that i am talking about is this one:

The problem is that after i put my own equations, parameters,...

dear sir, I want to use maplesim to import the modelica model of truetime network, but failed. the model is writen in modelica 2, is there any way to sovle this problem?

Hi all,

A while ago, I had asked a question relating to calling to an MapleSim .msim simulation within maple .mw worksheet. (Thank you Acer! :) I got it working but then another issue just popped up...The basic structure is as follows:

********************************************************************

A := MapleSim:-LinkModel('filename' = "TriplePendulum_WORKS_v2.msim")

for z from 1 to 50 do

     initialize_variables;

Liquid flowing in a pipeline has inertia.  If a valve at the end of the pipeline suddenly closes, a pressure surge hits the valve, and travels through the pipeline at the speed of sound. The damping effect of fluid friction gradually attenuates the pressure wave.

This phenomenon is called water hammer and can cause damage significant damage, sometimes even rupturing the pipeline.

The pressure wave often produces audible sound. If you’ve ever heard...

I think this is a simple question.  I have a gear train that has an input rad/s and an output rad/s.  I need the output speed graph to read in mm/s.  Basically I just need to multiply the rad/s by 2(Pi) to get rps and then multiply the rps by 2(pi)r to get mm/s.

I'm a university student trying to solve a problem, we've been given a very little maplesim knowledge, mostly gear related.  If someone can help me make a custom probes or plots that would be appreciated.
