MapleSim 2018 Questions and Posts

Dear Community,

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)

Tx for the kind help in advance,

best regards

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.

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.


I use MapleSim to model the dynamics of motorcycles.
I have been at MapleSim2018 for a few months and I have a problem of simplifying the equations generated by MapleSim from my model.
In MapleSim2018, he tells me:

Processing Equations...
SelectCompiler: Check for installed compiler successful
Simplifying system with 8919 equations
DSN/ix1lite: Warning, equation size increased past 100000 while performing equation simplification. Model will be simulated in partially unsimplified form
Simplification removed 8428 equations. Remaining equations: 491
Generating simulation code


the same model (exactly the same) in MapleSim2016, he tells me :

Processing Equations...
Simplifying system with 8942 equations
Simplification removed 8494 equations. Remaining equations: 448
Generating simulation code

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)

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!).

I need help, if it is possible to activate the complete simplification in DSN / ix1lite?

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.






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.
