BaseModelica.jl: BaseModelica Importers for ModelingToolkit.jl

BaseModelica.jl is an interface for the SciML open source software organization for importing BaseModelica, a new standard from the Modelica association for lowered Modelica code. As such, it makes it easy to import Modelica models into ModelingToolkit.

Installation

To install BaseModelica.jl, use the Julia package manager:

using Pkg
Pkg.add("BaseModelica")

API

BaseModelica.parse_basemodelica — Function

parse_basemodelica(filename::String)::ODESystem

Parses a BaseModelica .mo file into a ModelingToolkit ODESystem.

Example

parse_basemodelica("testfiles/NewtonCoolingBase.mo")

Info Packages marked with ⌃ and ⌅ have new versions available. Those with ⌃ may be upgradable, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated -m`

You can also download the manifest file and the project file.
