How does my licence work

A Flood Modeller licence, whether it's standalone, networked or cloud, enables a single user to run a specified number of concurrent simulations. The is determined by the edition of Flood Modeller you are using; Unlimited provides 4 instances, Professional provides 3 instances, Standard provides 2 instances and Lite provides 1 instance. 

A single user is defined as a user with the same username, using the same machine (hostname, IP Address, etc.) and other limitations placed by the WIBU StationShare methodology (see definitions below). 

Network and cloud licences use two licensing models; StationShare and UserLimit. This behaviour is inherited from the Codemeter licencing system provided by WIBU. The definition of these two licence models according to Codemeter documentation is:

UserLimit: this is used to control the number of licences issued. For each started instance of Flood Modeller, exactly one licence is allocated. The number of licences available for use under UserLimit is equal to the number of Flood Modeller licences available.

StationShare: this is effectively used as a "counter" of the number of concurrent simulations. For each combination of machine+user+session, only 4 instances of Flood Modeller based on the Unlimited edition (or 3 for Professional, 2 for Standard and 1 for Lite) are allowed and one licence is allocated. StationShare licences cannot be shared between sessions.

For example, one user of the Professional edition trying to run two models on one machine will need to be allocated one licence with UserLimit and two licences with StationShare. In order to clarify the terminology for the StationShare model, the following terms are explained:

• Machine: any physical or virtual machine that acts as a client, meaning it is requesting licences from a server machine.
• User: any user of the machine that has a unique login ID.
• Session: any local or remote access of a user to a machine. Not related to Flood Modeller instances.

There is a caveat for remote sessions for network and cloud licences. Each time a user logs onto a Windows machine using remote session, a different session/user ID is assigned to them. Any attempt to run a new instance of Flood Modeller will make the software seek for a new set of licence (UserLimit + StationShare), even if any previous sessions of the same user, on the same machine have unused StationShare licences.
