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 orchestra2021.jar file (or the runorchestra.bat file on Windows) within the folder.

You just need a computer with Java 8 installed!
