Hi,
Welcome to Openmodelica. Openmodelica is very good software and very userfriendly.
And it comes with lots of examples. First you should try to reproduce example models. Check the kinds of components they're using in the examples, and then try to reproduce the same. That should get you started.

Having said that, check out this link - https://www.youtube.com/watch?v=1Ke7KNipPds

Also, remember that you cannot connect a resistor to a gear directly. The point is, you can not randomly connect to elements.

All the best.

Topic: VehicleInterfaces Library Example Not working

Examples in the VehicleInterface library are not working properly.

Category: Usage and Applications

Forum: OpenModelica Usage and Applications

Hi Friends,
I've downloaded the vehicle interfaces library available. Now the problem is, it may not loading properly (at least examples).
I tried two examples - Conventional Automatic Vehicle, and the model icons were not loading properly, but I think simulation went good. I've attached the image.

And then I tried Rear wheel Drive automatic vehicle. In this example, unfortunately, I could neither see the icons nor could run example properly. I've attached the image, and also, these are the errors I got.

1] 17:51:23 Symbolic Error
Too many equations, over-determined system. The model has 2001 equation(s) and 1990 variable(s).

[2] 17:51:23 Translation Error
Internal error pre-optimization module clockPartitioning failed.

[3] 17:51:23 Symbolic Error
[VehicleInterfaces.Mechanics: 183:7-183:21]: Found equation without time-dependent variables: driverEnvironment.brakePosition.flange_a.f = 0.0

How do I debug it? How do I check if model is properly loading?

Please let me know what I can do to resolve issue. Thank you very much.

I did update, and it seems to be working.. Will let you know if I face problem in future.
thanks so much... current/smile

Thanks so much for early reply!

I'm not sure if I know correct way to check version of OMEdit.
But in About - I saw this one...
Connected to OpenModelica 1.9.2+dev (r23121)

As I said, I'm using nightly build on debian linux OS, and I do update every now and then. Last time updated was on weekend, Saturday, I think.

Errors while creating models in OMEdit - Variables/Components not defined?

Hi!
I'm trying to create models in OMEdit, but not able to do so properly because it's throwing error - "Not Found in Scope" repeatedly. This was not for just one model, but for different models I tried to create. I'm using linux version of openmodelica - nightly build.
When I tried to create basic electric circuit, I got the set of equations like this - with model name "ele"

model ele
equation
connect(constantvoltage1.p, ground1.p) annotation(Line(points = {{10, -20}, {-79.9235, -20}, {-79.9235, -29.4455}, {-79.9235, -29.4455}}, color = {0, 0, 255}));
connect(inductor1.n, constantvoltage1.n) annotation(Line(points = {{50, 40}, {55.8317, 40}, {55.8317, -19.5029}, {30.2103, -19.5029}, {30.2103, -19.5029}}, color = {0, 0, 255}));
connect(resistor1.n, inductor1.p) annotation(Line(points = {{-10, 40}, {30.5927, 40}, {30.5927, 39.3881}, {30.5927, 39.3881}}, color = {0, 0, 255}));
connect(ground1.p, resistor1.p) annotation(Line(points = {{-80, -30}, {-80.3059, -30}, {-80.3059, 39.7706}, {-29.8279, 39.7706}, {-29.8279, 39.7706}}, color = {0, 0, 255}));
annotation(Icon(coordinateSystem(extent = {{-100, -100}, {100, 100}}, preserveAspectRatio = true, initialScale = 0.1, grid = {2, 2})), Diagram(coordinateSystem(extent = {{-100, -100}, {100, 100}}, preserveAspectRatio = true, initialScale = 0.1, grid = {2, 2})));
end ele;

I should see the components in the "text view" of model, right? But I'm only seeing equations but not definitions of components.
I'm also attaching the screenshot.
The errors I'm seeing -

[/home/***********/ele.mo:3:3-3:162] Error: Variable constantvoltage1.p not found in scope ele.
[:0:0-0:0] Error: Error occurred while flattening model ele

I remember seeing same kind of errors in different models also, so I suspect this to be a generic problem. Can anybody suggest what i might be doing wrong or is it the problem with OMEdit?
Please let me know.

Thank you in advance.
