Dear any body,

I have tried several models/documents (with diagrams) using maplesim v7 32/64bit, but the simulation can not finish and in  equation generation a message appear as follow "protype must be a sructured record type or a record, but receipt squeezed".Same mesaages also appear if I try all examples exist in maplesim. What a big problem this?

Please help me..thanks in advance

Hi everybody,

is it possible to define an homokinetic joint in MapleSim for multibody modeling? How can I do that?

 

thanks.

Hello,

Is it possible to hide the geometry linked to the center of gravity and masses in the implicit geometry and keep only the kinematic joint.

If yes, may you explain how ? For the moment, I only manage to show/hide all the element of the implicit geometry. 

I use MapleSim 6.4.

Thank you for your help.

 

Hi,

I used to use windows 32 bit, but I have 64 bit windows now. I installed the MapleSim 6.4 and Maple 18 and try to run the simulations that I created with the 32 bit windows. I have this error 'Unable to compile (rc=1), please try again, and if that fails verify your Windows compiller installation'. Could you please let me know what should I do to eliminate this problem?

Best

Hello,

I would like to copy/ paste my maplesim model in microsoft visio.

The idea is to create a vectorial illustration for presentation.

I manage to do this with simulink but not with Maplesim.

Apparently, when I go in visio, there is no possibility to copy like a metafile.

Is there a possibility to copy the object of a Maplesim model in a software like visio or illustrator so as to be able to create vectorial illustration for presentation ?

Thank you for your help.

Hello,

I am quite new on Maple and Maplesim. A co-worker and I are evaluating a demo version (Maple 18 with Maplesim 7) for a possible purchase in 2015. For the project my collegue and I are working on, we need to detect when a signal becomes zero in order to switch between two options. We were trying to do this using the "Change" or "Boolean Change" components (the difference between those two is not really clear to us). Correct me if I am wrong, but those components should detect when a boolean signal has a change in value (both rising or decreasing) and in that case the output should become TRUE, while otherwise is FALSE.

The problem is that the component work if a "Terminate" is connected, but the output is always FALSE in any other case.

At the bottom we are attaching a file with two very easy examples.

In the first one the input of the "Boolean Change" component is a "Boolean Pulse". We compared also the output of the "Change", "Rising Edge", and "Edge with Initial Value" components. We were expecting istantaneous pulse with frequency equal to that of the boolean pulse, or its half for the Edge block. On the contrary the output of all the components stays zero (thus FALSE) for the whole simulation.

The second example use the output of a "Greater Threshold" component to enter the "Boolean Change", whose output is used to trigger a "Switch", whose output is in turn used as an input for the "Greater Threshold" component. The expected result is to have the "Switch" output to alternate the two inputs, instead it keeps the second one (thus the input for the switch is always FALSE).
The feature we need is more similar to this second output, but we don't understand what we are doing wrong or if there is another way to do it.
Thank you in advance
Irene

Dear Community,

Does anybody know, if there is a limit for the maximum number of equations for MapleSim? I tried with a system of 4456 equations, and I got the error message "(in DSN/RunSimulation ) system is inconsistent" When I took away most of the components (subsystems) it worked. So I suppose there must be some limit for the number of equations.

Tx in advance,

Andras

Hi,

I have a problem with a 1D loockup table with a Data set file. It seems that there are some problems with the file but I don't understand which.

 

I tried to use a .xlsx file and the result is this error (note that the table in excel has 17 rows, so at the 18 there is nothing):

 

Then I tried with a .csv file and I had this error:

I put below the MapleSim file, is not completed: just to have a look at the errors and the attached file, so don't consider other things.

srpingdamper.msim

the .xlsx attached files is the following, while i'm not able to upload the .csv but it's the same one just saved as .csv:

damperTR.xlsx

 

Thanks a lot.

 

Hey guys,

i'd like to create a custom component for maplesim. I opened the template in maple18 and defined the following equations:

eq := [p(t) = p__0+rho*g*h(t), Q(t) = A*(diff(h(t), t)), L(t) = 100*h(t)/h(0)]

These equations describes a tank with a liquid in it. Now I tried to define a function L(t) (above) that gives the level of the tank in percentage. Therefore I need the initial height value at t=0. The function defined above (h(0)) does not work, cause maple tells me that the function does not exist.

Any hint how to get an initial value or a value at t=0? Or maybe another way to solve my problem?

Hopefully I described right. :-)

Best regards

Christian

We have just released a new version of MapleSim.

MapleSim 7 makes it substantially easier to explore and validate designs, create and manage libraries of custom components, and use your MapleSim models with other tools. It includes:

  • Easy model investigation. A new Results Manager gives you greater flexibility when it comes to investigating your simulation results, including the ability to compare simulation runs on the same axes, instantly plot both probed and unprobed variables, and easily create custom plots.
  • Convenient library creation. With MapleSim 7, it is significantly easier to create, manage, and share libraries of custom components.
  • Improved Modelica support. MapleSim 7 expands the support of the Modelica language so that more Modelica definitions can be used directly inside MapleSim.

We have also updated and expanded the MapleSim 7 family of add-on products:

  • The new MapleSim Battery Library, which is available as a separate add-on, allows you to incorporate physics-based predictive models of battery cells into your system models so you can take battery behavior into account early in the design process. 
  • The MapleSim Connector for FMI, which allows engineers to share very efficient, high-fidelity models created in MapleSim with other modeling tools, has been expanded to support more export formats for co-simulation and model exchange.

See What’s New in MapleSim 7 for more information about these and other improvements in MapleSim.

Hi,

I need to build a multibody model in MapleSim 6.4 in which with few global parameters I can describe all the other parameters. In other words the final user will enter this few parameters, that are coordinates of specific points, and then the model will calculate all the relative distances on the base of those coordinates.

The problem is that if I apply trigonometric function and square root (like in the screenshot) the model is not calculating any value. Is it possible to make those calculculations?

 

this is the model (don't worry about the nonsense plots, it's because it's not ultimated):

DWS.msim

 

 

Thanks.
