BaseModelicaLibraryTesting.jl

Experimental Base Modelica library testing based on Julia.

Library Testing

For a given Modelica library test

1. Base Modelica export (OpenModelica, OMJulia.jl)
2. Base Modelica parsing (BaseModelica.jl)
3. ODE simulation (ModelingToolkit.jl, DifferentialEquations.jl)
4. Validating simulation results

Usage

main(
library ="<Modelica library name>",
version ="<Modelica library version>",
filter ="<Modelica class filter>",
omc_exe ="path/to/omc",
ref_root ="path/to/ReferenceResults"
)

If reference results are available provide the path via ref_root.

Example - Testing the Modelica Standard Library v4.1.0

For example, for the Modelica Standard Library v4.1.0 reference results can be obtained by cloning the MAP-LIB_ReferenceResults repository:`

git clone --depth 1 -b v4.1.0 https://github.com/modelica/MAP-LIB_ReferenceResults

Run the library testing for the ChuaCircuit example of the Modelica Standard Library v4.1.0 with:

using BaseModelicaLibraryTesting
main(
library ="Modelica",
version ="4.1.0",
filter ="Modelica.Electrical.Analog.Examples.ChuaCircuit",
omc_exe ="omc",
ref_root ="MAP-LIB_ReferenceResults"
)

Preview the generated HTML report at main/Modelica/4.1.0/report.html.

Changing the ODE Solver

By default the simulation uses Rodas5P(). To switch to a different solver, call configure_simulate! before main:

using BaseModelicaLibraryTesting
using DifferentialEquations
configure_simulate!(solver =FBDF())
main(
library ="Modelica",
version ="4.1.0",
omc_exe ="omc",
ref_root ="MAP-LIB_ReferenceResults"
)

Any SciML-compatible ODE/DAE algorithm (e.g. QNDF(), Rodas4()) can be passed to solver.

python -m http.server -d results/main/Modelica/4.1.0/

GitHub Actions — Manual MSL Test

The MSL Test & GitHub Pages workflow runs automatically every day at 03:00 UTC. It can also be triggered manually from the GitHub Actions UI:

1. Go to Actions → MSL Test & GitHub Pages
2. Click Run workflow
3. Fill in the options and click Run workflow

The following inputs are available:

Input	Default	Description
library	Modelica	Modelica library name
lib_version	4.1.0	Library version to test
bm_version	main	BaseModelica.jl branch, tag, or version
bm_options	scalarize,moveBindings,inlineFunctions	Comma-separated --baseModelicaOptions passed to OpenModelica during Base Modelica export
filter	^(?!Modelica\.Clocked)	Julia regex to restrict which models are tested (empty string runs all models)
solver	Rodas5P	Any DifferentialEquations.jl algorithm name (e.g. Rodas5P, Rodas5Pr, FBDF)

Results are published to GitHub Pages under results/<bm_version>/<library>/<lib_version>/.
