License System

TRNSYS commercial licenses can be purchased in packages of 1, 5, 10, 20, 30, 40, or 50 users for a given site. A site is defined as a departement of a given company at a specific location, which is the TRNSYS license holder. For the purposes of this license agreement, a location is defined as a physical local. Branch offices of a single enterprise are considered to be separate locations. All users must be affiliated with the TRNSYS license holder.

Educational licenses are to be used for educational and research purposes at degree-granting institutions only (other non-profit organizations such as governments do not count as educational). Each educational license is a site license and can be purchased in packages of 10, 20, 30, 40, 50, 60, or 70 users for that specific department or research group. The TRNSYS license holder is the specific department or research group. TRNSYS may not be distributed to other labs in the same institution. All users must be affiliated with the TRNSYS license holder.

License Management
License holders can choose between two licensing options. Please note that mixing of these two variants is not possible:

Node-lock: Each TRNSYS license allows the user to install a single instance of the Software on a given computer. No more users than the number of users of the license purchased have the right to use the software at a given time (e.g. if a 10-user license is purchased no more than 10 users may use the software at a given time).

Floating license: The floating license allows a user to use a license from any computer that can access the license server via the internet and has the program installed. A central license server dynamically allows licenses to float on the network, instead of being tied to a specific computer. This system requires a permanent internet connection during the use of the software. No more users than the number of users of the license purchased have the right to use the software at a given time (e.g. if a 10-user license is purchased no more than 10 users may use the software at a given time).
