Scripting API¶

The following are short summaries of OpenModelica scripting commands. These commands are useful for loading and saving classes, reading and storing data, plotting of results, and various other tasks.

The arguments passed to a scripting function should follow syntactic and typing rules for Modelica and for the scripting function in question. In the following tables we briefly indicate the types or character of the formal parameters to the functions by the following notation:

String typed argument, e.g. "hello", "myfile.mo".
TypeName – class, package or function name, e.g. MyClass,
Modelica.Math.
VariableName – variable name, e.g. v1, v2, vars1[2].x, etc.
Integer or Real typed argument, e.g. 35, 3.14, xintvariable.
options – optional parameters with named formal parameter passing.

The rest are the substrings that you wanted.
For example:

=> {" ipsum dolor ","ipsum","dolor"}
This means if you have n groups, you want maxMatches=n+1

function regex
  input String str;
  input String re;
  input Integer maxMatches = 1 "The maximum number of matches that will be returned";
  input Boolean extended = true "Use POSIX extended or regular syntax";
  input Boolean caseInsensitive = false;

end regex;

Simulation Parameter Sweep¶

Following example shows how to update the parameters and re-run the simulation without compiling the model.

loadFile("BouncingBall.mo");
getErrorString();
// build the model once
buildModel(BouncingBall);
getErrorString();
for i in 1:3 loop
  // We update the parameter e start value from 0.7 to "0.7 + i".
  value := 0.7 + i;
  // call the generated simulation code to produce a result file BouncingBall%i%_res.mat
  system("./BouncingBall -override=e="+String(value)+" -r=BouncingBall" + String(i) + "_res.mat");
  getErrorString();
end for;

We used the BouncingBall.mo in the example above. The above example produces three result files each containing different start value for e i.e., 1.7, 2.7, 3.7.

Examples¶

The following is an interactive session with the OpenModelica environment including some of the abovementioned commands and examples. First we start the system, and use the command line interface from OMShell, OMNotebook, or command window of some of the other tools.

We type in a very small model:

model Test "Testing OpenModelica Scripts"
  Real x, y;
equation
  x = 5.0+time; y = 6.0;
end Test;

We give the command to flatten a model:

>>> instantiateModel(Test)
class Test "Testing OpenModelica Scripts"
  Real x;
  Real y;
equation
  x = 5.0 + time;
  y = 6.0;
end Test;

A range expression is typed in:

>>> a:=1:10
{1,2,3,4,5,6,7,8,9,10}

It is multiplied by 2:

>>> a*2
{2,4,6,8,10,12,14,16,18,20}

The variables are cleared:

>>> clearVariables()
true

We print the loaded class test from its internal representation:

>>> list(Test)
model Test "Testing OpenModelica Scripts"
  Real x, y;
equation
  x = 5.0 + time;
  y = 6.0;
end Test;

We get the name and other properties of a class:

>>> getClassNames()
{Test,ProfilingTest}
>>> getClassComment(Test)
"Testing OpenModelica Scripts"
>>> isPartial(Test)
false
>>> isPackage(Test)
false
>>> isModel(Test)
true
>>> checkModel(Test)
"Check of Test completed successfully.
Class Test has 2 equation(s) and 2 variable(s).
2 of these are trivial equation(s)."

The common combination of a simulation followed by getting a value and doing a plot:

>>> simulate(Test, stopTime=3.0)
record SimulationResult
    resultFile = "«DOCHOME»/Test_res.mat",

Interactive Function Calls, Reading, and Writing¶

We enter an assignment of a vector expression, created by the range construction expression 1:12, to be stored in the variable x. The type and the value of the expression is returned.

>>> x := 1:12
{1,2,3,4,5,6,7,8,9,10,11,12}

The function bubblesort is called to sort this vector in descending order. The sorted result is returned together with its type. Note that the result vector is of type Real[:], instantiated as Real[12], since this is the declared type of the function result. The input Integer vector was automatically converted to a Real vector according to the Modelica type coercion rules.

>>> loadFile(getInstallationDirectoryPath() + "/share/doc/omc/testmodels/bubblesort.mo")
true
>>> bubblesort(x)
{12.0,11.0,10.0,9.0,8.0,7.0,6.0,5.0,4.0,3.0,2.0,1.0}

Now we want to try another small application, a simplex algorithm for optimization. First read in a small matrix containing coefficients that define a simplex problem to be solved:

>>> a := {
  {-1,-1,-1, 0, 0, 0, 0, 0, 0},
  {-1, 1, 0, 1, 0, 0, 0, 0, 5},
  { 1, 4, 0, 0, 1, 0, 0, 0, 45},
  { 2, 1, 0, 0, 0, 1, 0, 0, 27},
  { 3,-4, 0, 0, 0, 0, 1, 0, 24},
  { 0, 0, 1, 0, 0, 0, 0, 1, 4}
}
{{-1,-1,-1,0,0,0,0,0,0},{-1,1,0,1,0,0,0,0,5},{1,4,0,0,1,0,0,0,45},{2,1,0,0,0,1,0,0,27},{3,-4,0,0,0,0,1,0,24},{0,0,1,0,0,0,0,1,4}}

function pivot1
  input Real b[:,:];
  input Integer p;
  input Integer q;
  output Real a[size(b,1),size(b,2)];
protected
  Integer M;
  Integer N;
algorithm
  a := b;
  N := size(a,1)-1;
  M := size(a,2)-1;
  for j in 1:N loop
    for k in 1:M loop
      if j<>p and k<>q then
       a[j,k] := a[j,k]-0.3*j;
      end if;
    end for;
  end for;
  a[p,q] := 0.05;
end pivot1;

function misc_simplex1
  input Real matr[:,:];
  output Real x[size(matr,2)-1];
  output Real z;
  output  Integer q;
  output  Integer p;
protected
  Real a[size(matr,1),size(matr,2)];
  Integer M;
  Integer N;
algorithm
  N := size(a,1)-1;
  M := size(a,2)-1;
  a := matr;
  p:=0;q:=0;
  a := pivot1(a,p+1,q+1);
  while not (q==(M) or p==(N)) loop
    q := 0;
    while not (q == (M) or a[0+1,q+1]>1) loop
      q:=q+1;
    end while;
    p := 0;
    while not (p == (N) or a[p+1,q+1]>0.1) loop
      p:=p+1;
    end while;
    if (q < M) and (p < N) and(p>0) and (q>0) then
      a := pivot1(a,p,q);
    end if;
  if(p<=0) and (q<=0) then
     a := pivot1(a,p+1,q+1);
  end if;
  if(p<=0) and (q>0) then
     a := pivot1(a,p+1,q);
  end if;
  if(p>0) and (q<=0) then
     a := pivot1(a,p,q+1);
  end if;
  end while;
  z := a[1,M];
  x := {a[1,i] for i in 1:size(x,1)};
  for i in 1:10 loop
   for j in 1:M loop
    x[j] := x[j]+x[j]*0.01;
   end for;
  end for;
end misc_simplex1;

Then call the simplex algorithm implemented as the Modelica function simplex1. This function returns four results, which are represented as a tuple of four return values:

>>> misc_simplex1(a)
({0.05523110627056022,-1.104622125411205,-1.104622125411205,0.0,0.0,0.0,0.0,0.0},0.0,8,1)
