I have been messing around with MapleSim for a while now, and I cannot find a good way to model something such as a spiderweb. I want to be able to model a spiderweb (using something like cables), and then measure the tension in the cables, and also vibrations as they travel through the cables. Is this something that I can accomplish using MapleSim? If so, what is the best way to approach this problem? Any suggestions or comments would be helpful. Thanks.

I am trying to plot a Linear Population Model using Maple, could anybody tell me what I am doing wrong. My plot is just registering as a straight line at 1.0 and I know this is incorrect.

1 Introduction

Three tanks are connected with two pipes. Each tank is initially filled to a different level. A valve in each pipe opens, and the liquid levels gradually reach equilibrium. Here, we model the system in MapleSim (including the influence of flow inertia), and also derive and solve the analytical equations in Maple.

Hi,

I have an inverse kinematics model for a double inverted pendulum. There are multiple solutions for each joint angles due to symmetry and I have to choose the appropriate ones. I thought I can use the previous choices and compare them with the current multiple solutions, so I could choose the ones which are closer to the previous ones. However, since the double inverted pendulum moves in in both region at the equilibrium, this aproach does not work. Could you advise...

Dear All,

Im trying to model a rigid body, hanging from a string. In the end I have a system of 5 Equations of Motion and with all the Initial conditions I use dsolve. It gives me the error

Error, (in dsolve/numeric/DAE/isolate) is not linear

I know the system is not lnear but that should be not a problem. One strange thing I notice is that Maple adds these dots in some equations: (the one after 15 but please see original file)

15.*cos(`ϕz`(t...

The model that i uploaded (EqQui.msim) has a component with severall output and 4 inputs, but 2 of the inputs (LgKph2o and Lgkpco2) depends on one of the outputs. The 2 interpolation tables transfor the output variable (temperature) in this two inputs. All components works fine independtly (first "model", the one on the top), but if i link the exit of both interpolation tables mapleSim say it cant solve a lot of variables.

If I have a MapleSim file that successfully runs and I want to manipulate the data and equations in Maple, how would I do that? I know how to link a MapleSim file to a Maple document, and how to pull out the system of reduced DAE's, ODE's, parameters, etc. My question is whether or not there's a simple way to have Maple solve those equations and be able to display the same type of data (graphs, export the numerical solution to the system to an Excel file, etc.) that...

hi

so ill preface this by saying my knowledge of DE equations is rusty at best and my knowledge of maple even worse so this may be a stupid question. im trying to model the dynamics of a system and when i solve for the DE equation it's giving me an accleration of zero (plotting a blank graph) when it definitely shouldnt be. ive attached the worksheet.

Hi there,

I have created an animated plot of a modelled beam under sinusoidal forcing. It shows the beam bending along the x-axis. I was wondering how to plot the animated function with the beam lying along the y-axis instead of the x-axis as happens when i use the following command:

animate(w,x=0..1,t=0..0.1,frames=150,numpoints=100,color=red,thickness=3);

Any idea's?

hiI 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,...

I am trying to model a multibody system using euler lagrange equation. There are 3 links in the system attached with each other by revolute joints. The first link has one end fixed with the revolute joint.

Length of links= l1,l2,l3

Angle with x axis=Theta1,Theta2,Theta3

Mass of links=m1,m2,m3

Moment of Inertia = M1,M2,M3

I am not able to find the solution of ODE system comprising of 3 ODEs which I get after solving Euler Lagrange Eq for...

I'm suggesting a challenge to someone who can create a simulation in Maple on a local economy when a large supercenter enters, first, a localized small area (town), then the effect on a much larger population (state / country / etc...). A sort of local vs. large businesses.

I would like to create a business model that shows the eventual crash of rich economies due to the increased reliance on foreign imports from poor economies. As an example, perhaps...

Hi!

Sorry for my english, I'm french! :)

I try to make a modelisation of pedestrian dynamics.

Look:

There's someone, (a dot in Maple) at some randomn place in a square.

He want to go to another place.

So, there's 3 dot in Maple:

- S: The start fixed

- X: Mr X who is traveling from S to E

- E: The end fixed

so, without any rule, X is drawing a line from S to E.

Hello!

Could you pleasу tell me, is it possible to make MapleSim not to simplify equation set of my model and solve equations without simplification? I want to do this because simplification process (reduction of equations number) takes too much time in comparison with integration process.

Thank you!
