I have tried this with 1.14.0 dev but it is still not working. It is showing error that the array dimension must be known at compile time.

How to set annotations for library(line size, line color, line type, canvas size, grid or no grid canvas etc)?

We are indeed working on fixing library issues with newer version. Thanks a lot for your help. 

Yes. Thank you. But I am using OpenModelica 1.11 due to some compatibility issues for the library I am working on. Is it possible to update OMEdit to newer version and use OpenModelica 1.11?

I want to pass value of 'm' to instantiated models and use it as array size, but while compiling it is saying array size of 's' is not defined, you need to define array size while compiling. Is there any other way to do this except specifically writing (m = m) while instantiating?

package Test



  model one

    outer parameter Integer m;

    Real s[m];

  equation

    s = fill(7, m);

  end one;

  

  model three

    inner parameter Integer m = 2;

    one to, th;

  end three;



end Test;

I have attached model which was working in previous build and giving error

"LOG_NLS_V | warning | <p>proper start-values for some of the following iteration variables might help</p>
LOG_NLS_V | warning | <p>[1] Real $cse5(start=0, nominal=1)</p>"

Please run test model from attached package.

I am trying to solve optimization problem with CLI. I have attached file. I am running "optimize(opr, numberOfIntervals = 10, stopTime = 1, tolerance = 1e-5)" this command in CLI. But it is not showing answer in message window. Instead it gives me the path of .mat file and when I am opening that file using OMEdit it only contains "3".

Why is this happening?

I am also facing the same problem. Can someone please reply?

I am working on a model where multiple instantiation of model is required and some equations are written in new model where these model are instantiated.

I am instantiating "reboiler" model in "column". There is one array variable called mixMolFrac[2] in reboiler. I need to assign different values to this variable hence I am using if-else conditions. My if- else also coming inside for loop hence I am writing this in algorithm section since  writing it in equation section was producing some extra equations.

When I write it in algorithm in if- else as "reboiler.mixMolFrac[:] := {0, 0}"  it is showing

  [19] 01:26:52 Translation Error
Internal error checkAndGetAlgorithmOutputs failed.

[20] 01:26:52 Translation Error
No system for the symbolic initialization was generated

But if I write this in equation as "reboiler.mixMolFrac[:] = {0, 0}" without if-else, it is giving right results.

There are eight variables which I am writing in if-else in algorithm but only these  two variables are giving problem.

Thanks in advance.
Please reply asap

You can write "b = data.a.Tc". Also if you instantiate the Hydrogen model in testdata model and equate it to c then also it will work.

Although I am not sure why this error is coming.

When there is for and if-else in else part of if-else statement equations are not sorted. Please see the "main" in attached model. Why is this happening? Is there any alternative algorithm also if I want to do same thing in equation section. Is that possible?

Thanks.

Hi,

I want to calculate T in following model. I have made three models. In fist model (dewpoint) I am getting "Jacobian determinant is NaN" and "Invalid root: (1.#INF)^(2)" errors. I tried to simplify  and created second model (dewpoint1) . It is working and giving right results for two components. I tried same equations for three components in third model (dewpoint2) but it is showing error.

Why error coming in dewpoint2?

Is there any reference to learn about solvable systems in openmodelica and how to make other systems solvable?

Thank you in advance

Thank you very much. It have answered my all questions.

Thank you very much for instant reply.

I am new to coding. I have made enumeration of just names and then trying to assign value to record instantiated by general properties using if else statements. Since we can create drop down menu using enumeration which is not available as choices. I am trying to create model which can fully used with just GUI.

What do you mean by we need components not record in Database. Component is enumeration. enumeration cannot contain parameters and their values. I have more parameters also which are not given in code. Some of them are array.

Is it possible to define them inside enumeration? 

One different question. Is it possible to have different dialog boxes for different parameters in array. eg. If I want to make an array of Component component[2]. I have to write {Test1.Component.Air, Test1.Component.Argon} in GUI dialog box. So if we have different dialog box we can choose both by using drop down menu.

Is this making sense or am I missing something?

Thanks

Hi , I am working on creating models using OpenModelica at IITB. I am trying make model where component can be selected by using drop down menu. I have done it as shown in code.

package Test1
  type Component = enumeration(Air, Argon, Bromine, Carbontetrachloride, Carbonmonoxide);

  package Database
    extends Modelica.Icons.VariantsPackage;
    record General_Properties
      parameter Integer SN;
      parameter String name;
      parameter Real Tc;
      parameter Real Pc;
      parameter Real Vc;
      parameter Real Cc;
      parameter Real Tb;
      parameter Real Tm;
      parameter Real TT;
      parameter Real TP;
      parameter Real MW;
     
    end General_Properties;

    record Air
      extends General_Properties(SN = 1, name = "Air", Tc = 132.45, Pc = 3774000, Vc = 0.09147, Cc = 0.313, Tb = 78.67, Tm = 59.15, TT = 59.15, TP = 5642.15, MW = 28.96);
    end Air;

    record Argon
      extends General_Properties(SN = 2, name = "Argon", Tc = 150.86, Pc = 4898000, Vc = 0.07457, Cc = 0.291, Tb = 87.27, Tm = 83.8039, TT = 83.8, TP = 68906.1, MW = 39.948);
    end Argon;

    record Bromine
      extends General_Properties(SN = 3, name = "Bromine", Tc = 584.15, Pc = 1.03E+07, Vc = 0.135, Cc = 0.286, Tb = 331.9, Tm = 265.9, TT = 265.85, TP = 5853.37);
    end Bromine;

    record Carbontetrachloride
      extends General_Properties(SN = 4, name = "Carbontetrachloride", Tc = 556.3, Pc = 4557000, Vc = 0.276, Cc = 0.271, Tb = 349.79, Tm = 250.33, TT = 250.33, TP = 1122.46, MW = 153.822);
    end Carbontetrachloride;

    record Carbonmonoxide
      extends General_Properties(SN = 5, name = "Carbonmonoxide", Tc = 132.85, Pc = 3494000, Vc = 0.0931, Cc = 0.292, Tb = 81.66, Tm = 68.15, TT = 68.15, TP = 15400, MW = 28.01);
    end Carbonmonoxide;

   
  end Database;

  function get_comp
    extends Modelica.Icons.Function;
    output Database.General_Properties Comp;
    input Component component;
  algorithm
    if component == Component.Air then
      Comp := Database.Air;
    elseif component == Component.Argon then
      Comp := Database.Argon;
    elseif component == Component.Bromine then
      Comp := Database.Bromine;
    elseif component == Component.Carbontetrachloride then
      Comp := Database.Carbontetrachloride;
    elseif component == component.Carbonmonoxide then
      Comp := Database.Carbonmonoxide;
    end if;
  end get_comp;

model MS
  extends Modelica.Icons.SourcesPackage;
  parameter Component component;
  Database.General_Properties comp;
 
equation
  comp = get_comp(component);
end MS;

  model Test
    MS mS1(component = Test1.Component.Argon)  annotation(Placement(visible = true, transformation(origin = {-2, 48}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  end Test;
end Test1;

But I am getting type mismatch error. Is there any way to assign value to a record or a model in an algorithm or an equation section?

Also Is it possible to make separate dialog boxes for each parameter in an array, rather than using single box for all parameters in an array?

I am also getting similar error

I have written very simple code. But it is showing translation warning and errors. I have attached screenshot of code and error. I have read while loop and for loop description but not able to recognize meaning of these errors.
Please help.
