SystemModels

SystemModels[]

returns a list of loaded system models.

SystemModels[patt]

returns the models matching the string pattern patt.

SystemModels[patt,"spec"]

only returns specialized models of the kind "spec".

Details

  • SystemModels[patt] allows the same string patterns as StringMatchQ.
  • With SystemModels[patt,"spec"], only models with "spec" are returned:
  • "class"general class
    "model"model class
    "block"input/output block
    "connector"connector class
    "function"function definition
    "package"collection of classes and constants
    "record"collection class
    "type"type specification

Examples

open all close all

Basic Examples  (3)

Get all models currently available:

Wolfram Language code: SystemModels[]//Shallow

Show all examples in the Modelica rotational mechanics library:

Wolfram Language code: SystemModels["Modelica.Mechanics.Rotational.Examples.*"]

Get only a specific type of model:

Wolfram Language code: SystemModels["Modelica.Electrical.Analog.*", "connector"]

Scope  (1)

Use a StringExpression to get Modelica standard library examples containing q:

Wolfram Language code: SystemModels["Modelica." ~~ __ ~~ ".Examples." ~~ __ ~~ "q" ~~ __]

Applications  (1)

Get the number of each model type in the Modelica Standard Library:

Wolfram Language code: specs = {"class", "record", "type", "model", "block", "package", "function", "connector"};
Wolfram Language code: nrs = Map[Length[SystemModels["Modelica.*", #]]&, specs]
Wolfram Language code: PieChart[nrs, ChartLabels -> specs]

Do the same for "IntroductoryExamples" and "DocumentationExamples":

Wolfram Language code: Table[PieChart[Map[Length[SystemModels[lib <> ".*", #]]&, specs], ChartLabels -> specs, PlotLabel -> lib], {lib, {"IntroductoryExamples", "DocumentationExamples"}}]

Properties & Relations  (1)

SystemModelExamples returns only models that can be simulated:

Wolfram Language code: pattern = "Modelica.Mechanics.Rotational.*";
Wolfram Language code: simulationModels = SystemModelExamples["Models", pattern]

SystemModels returns all models, which is usually a much larger list:

Wolfram Language code: {Length[SystemModels[pattern]], Length[simulationModels]}
