TUFLOW

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

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

Licences¶

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
