I've tried in OMShell pendulum's exercise.
Simulation ok, but when I write plot(vx), OMShell give "true" but nothing happens.

same problem....

trying new exercise from Fritzon book, "pendulum":


Simulation failed for model: pendulum
ERROR: system(OPENMODELICAHOME=\"$OPENMODELICAHOME\" /opt/openmodelica/share/omc/scripts/Compile pendulum ) failed: Interrupted system call

I tried but OMEdit gives me same error.

I'm sad, becaus I don't want to use Windows....

What is login/logout?

lorenzotrombetta$ ls -lH /usr/bin/g++

Hi,
I installed XCode 3.2 for OS X Snow Leopard.
I tried to simulate this model:

model MassaForza "Massa spinta da una forza costante"
  parameter Real m = 2 "Massa del blocco";
  parameter Real f = 6 "Forza applicata";
  Real s "Posizione del blocco";
  Real v "Velocità del bloco";

equation
  v = der(s);
  m * der(v) = f;
end MassaForza;

Then I simulated, so plotting, but selecting variables nothing happens, it doesn't appear any graphs.

So I ri-pushed simulate and OMEdit gives it:

---- Error 2 : 19:42:42 ----
Unable to simulate the Model 'MassaForza'
Following Error has occurred.

Simulation failed for model: MassaForza
ERROR: system(OPENMODELICAHOME=\"$OPENMODELICAHOME\" /opt/openmodelica/share/omc/scripts/Compile MassaForza ) failed: Interrupted system call

Hi

I'm at home with my MacBook Pro, Mac OS X V. 10.6.8 and OM 1.6.0.
I've tried to simulate Hello World in OMShell and it doesn't work.

I post the result


class HelloWorld
   Real x(start=1);
parameter Real a = 1;
equation
   der(x)=-a*x;
end HelloWorld;
{HelloWorld}

>> simulate(HelloWorld)
record SimulationResult
    resultFile = "",
    simulationOptions = "startTime = 0.0, stopTime = 1.0, numberOfIntervals = 500, tolerance = 1e-06, method = 'dassl', fileNamePrefix = 'HelloWorld', storeInTemp = false, noClean = false, options = '', outputFormat = 'mat', variableFilter = '.*'",
    messages = "Simulation failed for model: HelloWorld
Error: Error building simulator. Buildlog: /opt/openmodelica/share/omc/scripts/Compile: line 2: make: command not found

Error: Error building simulator. Buildlog: command g++ not found. Check $OPENMODELICAHOME

    timeTemplates = 0.0,
    timeCompile = 0.0,
    timeSimulation = 0.0,
    timeTotal = 0.0
end SimulationResult;

Changed OS, new nightmare.
Please, help me....

So, I have the same problem with Mac.
At home I'll try nightly version.

Good Job!!!!

It works!!!!!

Thank you very much!

Lorenzo

Do I uninstall older version before install nightly?

Thanks,
Lorenzo

Hi Adrian

Windows SP3 on job desk with OpenModelica 1.8.0 (r10584)
at home MacPro 10.6.

What's the OM nightly version?

Regards,
Lorenzo

Per,
Also I tried OMEdit but I don't go so far....

I write my model, play simulate but nothing happens.
If I push Plotting button, there isn't any graph or any variables to select.

Sorry, I've searched on web but I haven't found anything.

Hi Adeel
I tried but it's the result:

class HelloWorld
   Real x(start=1);
parameter Real a = 1;
equation
   der(x)=-a*x;
end HelloWorld;
{HelloWorld}

>> simulate(HelloWorld)
record SimulationResult
    resultFile = "",
    simulationOptions = "startTime = 0.0, stopTime = 1.0, numberOfIntervals = 500, tolerance = 1e-006, method = 'dassl', fileNamePrefix = 'HelloWorld', storeInTemp = false, noClean = false, options = '', outputFormat = 'mat', variableFilter = '.*', measureTime = false, cflags = ''",
    messages = "Simulation failed for model: HelloWorld
",
    timeFrontend = 0.0,
    timeBackend = 0.0,
    timeSimCode = 0.0,
    timeTemplates = 0.0,
    timeCompile = 0.0,
    timeSimulation = 0.0,
    timeTotal = 0.0
end SimulationResult;

Thank you very much for your help, Per too.

Hi,
I'm new italian openmodelica user.
I've bought Peter Fritzson principles of object-oriented modeling and simulation with modelica, that proposes some easy exercise, like HelloWorld.

The first question is:
where do I have to insert script? In OMEdit Text View or in OMShell?

So, when I insert this script:

class HelloWorld
   Real x(start=1);
parameter Real a = 1;
equation
   der(x)=-a*x;
end HelloWorld;

simulate(HelloWorld);

plot(x)

OMEdit gives back this error message:


Syntax    14:24:31        8:1-8:8    Parser error: Unexpected token near: simulate (IDENT)

I haven't any ideas, so please help me.

Regards,
Lorenzo
