I'm attempting to run a linked Flood Modeller-TUFLOW model, which fails immediately with the following message in the TUFLOW log file

initialising M2D licence...
TUFLOW M2D Module       No free LAN licences available.

NoXY: ERROR 2100 - Multiple 2D Domains module not available or all licences in use.
Cannot use "Start 2D Domain" command.
For licensing information, please contact sales@tuflow.com.

We do have networked TUFLOW licenses, and it is correct that at the time none were available.  However, the set-up of the machine should mean that TUFLOW retries for a license until one becomes available.

This seems to have only become an issue since updating to the latest versions of Flood Modeller (4.3) and TUFLOW (2017-09-AC-iSP-w64).  Would anyone be able to advise on why the model fails, rather than retrying for a license?

Many thanks

Hi, I-Hsien

Thank you for your post on this forum.

We saw that the TUFLOW software is set up to only retry searching for license when mid-run, i.e. if it previously found a licence which dropped out mid-run.

Kind regards,
