In release r15749 OMEdit works again on a mac computer:-)

OMEdit crashes when starting!

I frequently install the nightly builds op openmodelica for the mac using ports.

Using omc and OMShell works oke. But for version 1.9 i was not able to get OMEdit working. It is there under applications/macports/. OMShell is also there in applications/macports/ and runs oke. Two folders are there, applications/macports/, Python 2.7 and Qt4.

It seems that there is a problem with Qt4. Do i need to set some environment variables?

kind regards
Dick

I'm using Ports to install that latest build of Open Modelica. The OMshell and the omc work oké. The OMshell and OMEdit are installed in the application directory. Until now i used emacs to develop and compile (omc) the modelica models, using the scripting (mos) files. This way i got some insight and experience with Modelica. Now it's time to switch to a graphical environment (OMShell)

When I start OMEdit on the Mac I get the following error. What could be wrong? (oh: I did not add any environment variables)

The problem was caused by the following line:

beta*(A*u)^2*(inlet.P - outlet.P) = inlet.mdot^2;

The solution method choose for inlet.mdot the negative value as the solution. It should have been the positive value, because the inlet.P pressure is higher than the outlet.P pressure.

So i changed the code to:

sqrt(beta*(A*u)^2*(inlet.P - outlet.P)) = inlet.mdot

Now all looks oké!

Is there a way of coding that can avoid such programmer "mistakes"?

I'm using r14545.

I also get a good result when I use OMShell and your script commands. (a.mo probably should be dck1.mo in your script?)

Although when I use the 'outputformat="csv" I do not get the same values in the 'csv' file!

Could you check this.

Below you find a model from the Modelica 2.1 book of Peter Fritzson. It simulates but the results are not oké.

The variable CtrlValveFlow.inlet.mdot looks correct, but the variable pressureEnthalpySource.outlet.p is zero (0) but should be 1.2e5. What could be wrong?

I do get the warning:
[dck1.mo:2:3-7:20:writable] Warning: Connector dck1.FlowConnector is not balanced: The number of potential variables (2) is not equal to the number of flow variables (1).
Is this the problem?

package dck1

  connector FlowConnector

    import Modelica.SIunits.*;

    Pressure              P;

    flow MassFlowRate     mdot;

    SpecificEnthalpy      h;

    import Modelica.SIunits.*;

    FlowConnector outlet;

    parameter Pressure P_0=1.0e5;

    parameter SpecificEnthalpy h_0=300190;

  equation

    outlet.P = P_0;

    outlet.h = h_0;

  end PressureEnthalpySource;



  model ControlledValveFlow

    import Modelica.SIunits;

    import Modelica.Blocks.Interfaces;

    FlowConnector           inlet, outlet;

    Interfaces.RealInput    u;

    parameter SIunits.Area  A = 1e-4;

    parameter Real          beta = 5.0e-5;

  equation

    // Conservation of mass

    0 = inlet.mdot + outlet.mdot;

    // Conservation of energy

    0 = inlet.mdot*inlet.h + outlet.mdot*outlet.h;

    beta*(A*u)^2*(inlet.P - outlet.P) = inlet.mdot^2;

    assert(inlet.P - outlet.P > 0, "Error: model not valid for backflow");

  end ControlledValveFlow;



  model PressureSink

    FlowConnector inlet;

    parameter Modelica.SIunits.Pressure P_0=1.0e5;

  equation

    inlet.P = P_0;

  end PressureSink;



  model CtrlFlowSystem

    import Modelica.Blocks.Sources;

    PressureEnthalpySource   pressureEnthalpySource(P_0=1.2e5);

    Sources.Step             step(offset=1,startTime=0.5,height=-0.5);

    ControlledValveFlow      ctrlValveFlow;

    PressureSink             pressureSink;

  equation

    connect(pressureEnthalpySource.outlet, ctrlValveFlow.inlet);

    connect(ctrlValveFlow.outlet, pressureSink.inlet);

end dck1;

Hello,

I' using version 1.9.0 beta 2.

I'm implementing the example Thermodynamics - an air filled control volume with subsystems (paragraph 15.2) from the book of Peter Fritzson. Things work-out oke.

But from paragraph '15.2.5.6 System and Valve Model with interfaces and Externally controlled flow' I get warnings and errors that I cannot solve. The model that started giving trouble is 'CtrlFlowSystem'.  I assume that 'ControlledFlowModel' should be 'ControlledValveFlow' but I get singular system errors and warning on unbalanced connector.

Did any of you implemented this example and did you have the same trouble? How did you solve it?

In a directory  i put a model file (Apollo12a.mo).

In a subdirectory named 'Core' i put the package files. package.mo, Body.mo, CelestialBody.mo, Rocket.mo.

In de file Apollo12a.mo i put the import Core; statement.

When i run the command 'omc Moonlanding.mos' i get the error message 'Class Core.CelestialBody not found'.
----
mos file:
loadFile("Moonlanding.mo");
simulate(MoonLanding, stopTime=230);
plot({apollo.altitude,apollo.thrust});
----


package file in the Core directory
------
within ;

encapsulated package Core "Contains the Core classes and models"

end Core;
------

Q: Where does omc look for the 'import Core' statement.

Adeel,

It works:-) The compiler is recognized.

Thanks very much. It was late last night for you 2:55:48 (early morning).

Hi,

I do get the "Openmodelica compiler null is online"

I use the following environment variables.
OPENMODELICAHOME=/opt/openmodelica
OPENMODELICALIBRARY=/opt/openmodelica/lib/omlibrary
Is this correct?

Dick

I installed the MDT plugging in eclipse.

I get the warning that it is no officially supported on OSX. Is this correct?

I also get the error "problems while communicating with the Open modelica compiler".
I use eclipse 4.2.0 and OMC 1.8.1.

OMEdit is working:-) So i assume the environment variables are set oké.
But i would like to use the features of MDT.

So the questions are: Should MDT work on the mac? If yes what should i check/adapt to get it working?

kind regards
Dick Barends

What is the correct line for the environment variable to the Standard Modelica Library (STL), so that OMEdit will automatically import the models library.
I downloaded version 3.1 of STL from the Modelica Web site. After unzipping i got a directory 3.1-build-6.

So it is something like: MODELICAPTH=/Users/dbarends/??????????

Could you give me some hints:-)

kind regards
Dick Barends

Thanks sjoelund, for the quick response, it solved the problem!

I'm using OpenModelica on a MAC. OSX 1.6.7.

OpenModelica devel-8719 and 9308  both say as i start OMShell that OPENMODELICAHOME env. variable is missing.

When i give the command env i see that the variable exists. Below the text from the terminal

"OPENMODELICAHOME=/opt/openmodelica/bin/"

What am i doing wrong?
