License Types

Node Locked

The node-locked license type grants the right to use the software on one (1) computer. This is sometimes referred to as a "fixed" or "single-computer" license.


The floating license type allows multiple computers on a network to share a PyroSim license. Each floating license of PyroSim can be used by one (1) computer at a time. When a user closes PyroSim, that floating license becomes available to other users on the network. You can purchase additional copies of the PyroSim floating license to enable simultaneous access by multiple computers. This is sometimes referred to as a "network" or "concurrent use" license.

If you need to work with the software without a network connection, you can request a short-term node-locked license from, please request the license with at least 2 business days of lead time to ensure we can provide the support you need.


Maintenance must be purchased annually after the first year to keep your version up-to-date and to receive technical support. Maintenance must be paid continuously to remain in effect.
