Complete self-contained system in zipped folder

The fastest way to get up and running is to download a complete example in a single zipped folder (ca 360 kB ). This folder includes the ORCHESTRA executable (.jar file), the standard object database (objects.txt), a thermodynamic database and input files defining  a simple example system.

ORCHESTRA can be started by clicking the orchestra2022.jar file (or the runorchestra.bat file on Windows) within the folder.

You just need a computer with Java 8 installed!

ORCHESTRA executable

The latest version of the ORCHESTRA2022.jar file  can be downloaded separately here.

This version is backward compatible with versions should work without changes with existing systems. However, new options (e.g. temperature dependent reactions) require the use of 2022 object and databases files

(This executable runs on any Windows/Mac OSX/ Linux machine that has Java 8 installed).
