TUFLOW

Hydraulic modelling software for flood, urban drainage, estuarine and coastal assessments. TUFLOW Homepage

Warning

TUFLOW is proprietary software. Make sure you meet the requirements for it's usage.

Solvers

The TUFLOW module provides two executables:

TUFLOW Classic (tuflow-idp, tuflow-isp): 1D/2D hydrodynamic solver using structured grids, controlled by a .tcf file. tuflow-idp for double floating point precision, tuflow-isp for single point.
TUFLOW FV (tuflowfv): flexible-mesh (finite volume) 2D/3D solver, controlled by a .fvc file.

Available Modules¶

module load TUFLOW/2026.0

Licence Connection¶

TUFLOW requires a background licence daemon to be manually launched before the solver. If you are using a network cloud licence, you will have to register it first.

CodeMeterLin -v &
sleep 10 && cmu --import --file ~/my_licence_key.wbc
