OMEdit

OMEdit, short for OpenModelica Editor, is the primary graphical user interface for the OpenModelica project. It provides an integrated environment for creating, editing, simulating, and analyzing Modelica models. OMEdit supports both graphical modeling and textual Modelica coding, and it works with the Modelica Standard Library and third-party libraries to build complex models.

The editor offers a drag-and-drop graphical editor to assemble models from components and connectors, a library browser to manage models and packages, and a properties editor to configure parameters, connections, and other attributes. In addition to the graphical interface, users can edit Modelica code directly in a built-in text editor, enabling a flexible workflow that combines visual modeling with code-centric customization.

OMEdit interfaces with the OpenModelica Compiler (OMC) in the backend to type-check, translate, compile, and simulate models. It includes features for setting up simulations and experiments, managing parameters and external inputs, and running batch or parameter sweep studies. Results are presented via integrated plot windows, a results browser, and options for exporting data for further analysis.

The application is cross-platform, running on Windows, Linux, and macOS, and is built with the Qt framework. As part of the OpenModelica open-source project, OMEdit serves researchers, educators, and developers by enabling fast modeling, visualization, and analysis of dynamic systems described by Modelica.
