MDT - Modelica Development Tooling

MDT screenshot

The Modelica Development Tooling (MDT) Eclipse Plug-In integrates the OpenModelica compiler with Eclipse. MDT, together with the OpenModelica compiler, provides an environment for working with Modelica projects.

The following features are available: [Cool Screen Dumps]

  • Browsing support for Modelica projects, packages, and classes
  • Wizards for creating Modelica projects, packages, and classes
  • Syntax color highlighting
  • Syntax checking
  • Browsing of the Modelica Standard Library
  • Simple code completion
  • Code indentation correction
  • Paranthesis matching
  • MetaModelica browsing and assistance
  • OpenModelica command console


MDT was developed by two loony undergraduate students in their eternal quest for a degree. They have finished with their master thesis in April 2006 and, since then, the responsible with maintaining and enhancing MDT is Adrian Pop. The work on the plugin is a part of the larger project by PELAB which aims to create a complete Modelica and MetaModelica modeling, compilation and simulation environment.

MDT is used at PELAB for the development of the OpenModelica compiler.


To use MDT you need the OpenModelica Compiler and Eclipse installed on your system.

You can find MDT documentation HERE.

You will also need Java 5.0 (aka 1.5) to use the plugin.



Here you can find an MDT installation howto.

The most convenient way to install MDT is by instructing Eclipse to fetch the plugin from the
update site which is located at
If you are not sure how to accomplish this, just follow the instructions below.

  • Start Eclipse
  • Select Help -> Software Updates -> Find and Install... from the menu
  • Select Search for new features to install and click Next
  • Select New Remote Site...
  • Enter MDT as name and as URL and click OK
  • Make sure MDT is selected and click Finish
  • In the updates dialog select the MDT feature and click Next
  • Read through the license agreement, select I accept... and click Next
  • Click Finish to install MDT

Another way to install MDT is by downloading a zip file, unzip it locally and point the Eclipse to the unpacked directory.

  • Download the latest zip file from here
  • The zip file will unpack to a local directory called "mdt"
  • Start Eclipse, then go Help->Software Updates...
  • Add the "mdt" directory as a local site (this is different from version to version) and then install the latest version of MDT from this local site.


A trac system is available for MDT, please contribute by reporting bugs.
