DC Motor Back EMF
https://www.mapleprimes.com/questions/226877-DC-Motor-Back-EMF?ref=Feed:MaplePrimes:Tagged With MapleSim
<p>Hi,</p>
<p>I have to model a DC motor in MapleSim. Reading the help of the component EMF I can't undestand if it takes into account also the Back EMF or if I have to use a voltage generator and a rotational speed feedback loop.</p>
<p>Do you know something about that?</p>
<p>Thanks.</p>

https://www.mapleprimes.com/questions/226714-How-To-Get-The-Numerical-Results-Of?ref=Feed:MaplePrimes:Tagged With MapleSim
<p>Dear Community,</p>
<p>I run a MapleSim model from Maple. The simulation runs fine giving me the correct graphical plots, but I wonder how could I obtain also the numerical values of the probes vs. time? Sorry I could not figure it out. A matrix format would be perfect: 1st column time, the other columns probe 1 .. n values vs. time. (Files attached)</p>
<p>Tx for the kind help in advance,</p>
<p>best regards</p>

<p>Dear Community,</p>
<p>I have set up a simple 2D RC network with 1 lookup table current source, and a few probes. The model runs fine. Now I wanted to run it from Maple, and followed carefully a MapleSim tutorial which exlained how to establish the link between Maple and MapleSim. I added a worksheet called RCNetworkMaple.mw and run the A := MapleSim:-LinkModel(): command. Then I wanted to run the simulation with the A := Simulate() ; command, but nothing happened, Maple returned A := Simulate(). What did I wrong? In the tutorial it runs perfectly. (Files attached.)</p>

https://www.mapleprimes.com/questions/226689-MapleSim--Inclined-Plane?ref=Feed:MaplePrimes:Tagged With MapleSim
<p>Hi,</p>
<p>I have to build a simple model in MapleSim that allows to simulate a mass that goes down along an inclined plane with a certain friction.</p>
<p>Is there a component that simulates the inclined plane? I tried to use a prismatic joint but it has some predifined translational directions so I can't impose the movement along the plane.</p>

https://www.mapleprimes.com/questions/226629-Big-MapleSim-Model-Cant-Be-Totaly-Simplified?ref=Feed:MaplePrimes:Tagged With MapleSim
<p>Hello,</p>
<p>I use MapleSim to model the dynamics of motorcycles.<br>
I have been at MapleSim2018 for a few months and I have a problem of simplifying the equations generated by MapleSim from my model.<br>
In MapleSim2018, he tells me:</p>
<p><span><span><span><span><span><span><span>Processing Equations...<br>
SelectCompiler: Check for installed compiler successful<br>
Simplifying system with 8919 equations<br>
DSN/ix1lite: Warning, equation size increased past 100000 while performing equation simplification. Model will be simulated in partially unsimplified form<br>
Simplification removed 8428 equations. Remaining equations: 491<br>
Generating simulation code</span></span></span></span></span></span></span></p>
<p> </p>
<p>the same model (<strong>exactly the same</strong>) in MapleSim2016, he tells me :</p>
<p><span>Processing Equations...<br>
Simplifying system with 8942 equations<br>
Simplification removed 8494 equations. Remaining equations: 448<br>
Generating simulation code</span></p>
<p>When I generate code from two versions of Maple (2016 and 2018) and compile it into an executable, the MapleSim 2018 executable runs 20% slower than the MapleSim 2016 version of the executable (the results and the behavior of both models are equivalent)</p>
<p>It is very strange that a new version of MapleSim generates a slower code than the old version. it may be due to the limitation of DSN / ix1lite in MapleSim2018 ... while MapleSim2016 does not have this limitation (with more equations to simplify!).</p>
<p>I need help, if it is possible to activate the complete simplification in DSN / ix1lite?</p>
<p>it is a big problem for me, the use of MapleSim2018 is not possible because of that. My model does not pass in real time.</p>
<p><span><span><span><span><span><span><span>thanks.</span></span></span></span></span></span></span></p>

<p>Let</p>
<p>b[n]+b[n-1]+b[n-2]=0, for all n greater or equal 3</p>
<p>b[1]=-1;</p>
<p>b[2]=0</p>
<p>b[0]=1</p>
<p> </p>
<p>How can we deduce the value of this sequence b[n] for all n</p>
<p>thanks</p>
