TUFLOW Message 0935

TUFLOW Message
CHECK 0935 - Licence lost. Count = ",a,". Pausing for ",a," seconds.

Alternate Message
NA

Message Type
CHECK

Description
Access to the licence has been lost.

As a background to the licencing, TUFLOW checks for a licence on model initialisation, and then periodically checks at a certain time interval, as well as at the end of the simulation. The CodeMeter licencing system used by TUFLOW will release any licences that are not in use after a period of time. This prevents the licence from being tied up forever by a force closed simulation (either closed through task manager or by clicking the red x at the top of the window).
This message indicates either TUFLOW could not find any licence during a periodic check, or the licence has been already released between two periodic checks.

Suggestions
Try plugging the licence dongle into a different USB port and/or on the different machine. Update your CodeMeter RunTime Kit, download available here: http://www.codemeter.de/us/service/downloads.html.

Prior to built 2018-03-AA the licence could get lost when the map output was very infrequent. The infrequent output could cause TUFLOW to drop the licence and attempt to re-take the licence after a long period. As a workaround, the map output frequency can be changed to more frequent or a small output zone can be set with more frequent output to invoke more frequent licence checks.

Rarely, the licence could get lost for the 2018 TUFLOW releases when the map output was infrequent and the model didn't have any 1D or hidden 1D structures e.g. a QT boundary. As a workaround, the map output frequency can be changed to more frequent, a small output zone can be set with more frequent output or a dummy 1D channel can be created to invoke more frequent licence checks.
