Hi people!

Why there is not a "Modelica.Mechanics.MultiBody.Joints.RollingWheel" (different from 1-D mechanics rolling wheel) in MapleSim 5? It is previewed in the Modelica language and SystemModeler has this implementation.

Is there a way to import the model o this joint from somewhere? If not, how could I model this non-holonimic constraint in MapleSim? 

Thanks! 

Hi there.

 

I build a costum component on maplesim. It has 2 inputs and several outpus, like this:

 

As you cant see i get an error. At this simulation the constant where is probe1 is k=4. I have good results if n=2-~3.5. But what is strange is that if instead of a constant input n=4, i use a...

I wanted to point the MaplePrimes community in the direction of the new MapleSim training videos. These videos cover a variety of common tasks within MapleSim, and demonstrate the concept in just a few minutes each. I'd highly recommend you take a look at them to learn more about using MapleSim.

MapleSim has seen a rapid evolution since its inception in 2008 as a multi-domain system-level modeling and simulation environment. Market response has been outstanding: Maplesoft has been working with an expanding list of key industry players such as AISIN AW Co., Ltd. and B&R,  while major customers like

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...

I have just started using MapleSim 5 and running the examples I got the following notification and don't know how to resolve it (to what options are being referred to and what is infolevel?):

Compiling...

(in dsolve/numeric/RunSimulation) unable to compile, please check your options by running with infolevel[ToExternal]:=1;

Simulation failed.

Not sure what (in DNS/RunSimulation) means but it preceeds my "simulation failed, an error occurred" note.

I made a model with mapleSim, run simulation and the following figure was got

Here I have a question. I want to know the max value of this curve that will be used in other component as input in mapleSim. Is here a component in mapleSim or other mothed such as maple?

please help me. think you

On Monday, August 6 at 1:31 a.m. EDT, NASA will attempt the landing of a new planetary rover, named Curiosity, on the surface of Mars.  The Mars Science Laboratory project is managed by the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California, a world-renowned center for robotic space exploration and advanced science and engineering.  JPL recently began a widespread adoption of Maplesoft technology, and Maplesoft’s products are expected to help JPL save...

Hi,

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.

I am currently working on a MapleSim model that is similar to the Stewart Platform, yet less complex. I have built a tripod that is fixed to the ground with three legs connecting to a platform. Connecting the leg to the ground is a revolute joint and connecting the leg to the platform is a spherical joint. When I change the initial conditions of the spherical joint from 'Treat as Guess' to 'Ignore' 2 of the 3 legs will change orientiation. I'm not sure why this occurs to only 2 legs, can someone help me?

I have created a wheeled robot in MapleSIM for my bachelor thesis and for various calculations I need the location of the center of mass.  I am unsure of how to find this.  Could you please help me and explain how to find this?  Thank you for your help.

I have got the following instructions of computing the required trajectories (orbits). They have been done with Maple V3. I cannot get them going with Maple 16. I have just started with Maple and cannot see the mistake in the instruction. Can anybody help me? Thanks!

hi,

I am trying to make a simple model of a combustion. To start i am just calculating the composition of the products for a complete combustion and flame´s adiabatic temperature. The equations used to solve the model are:

equations:

nch4 = nco2;
2 * nar = 2 * nco2 + nh2o + 2 * no2;
7.52 * nar = 2 * nn2;
4 * nch4 = 2 * nh2o;
nch4 * hfch4 + nar(hfo2 + 3.76 * hfn2) = nco2(hfco2 + cpco2(Tad - 25)...
