TUFLOW FV (which stands for Two-dimensional Unsteady FLOW Finite Volume) is a flexible mesh finite volume numerical model that simulates hydrodynamic, sediment transport and water quality processes in oceans, coastal waters, estuaries and rivers. The model may be used for coastal and nearshore environments including beaches and coastlines as well as offshore environments such as estuaries, river entrances and deltas, and floodplains. Uses include modeling river flood flow, tsunami inundation (the finite-volume scheme is well suited for a tsunami's mixed sub/super-critical flow regimes), beach erosion, ocean pollution, and estuary flow.

Unlike the fixed square grids of TUFLOW Classic, the flexible triangular or quadrilateral mesh of TUFLOW FV allows users to modify mesh resolution spatially, seamlessly increasing the model resolution in areas of interest. This modelling approach reduces the number of computation cells needed in a model reducing run times. Additionally, TUFLOW FV can be run in parallel on multiple processors, threads, or computers.

The TUFLOW FV model can be added to a paid edition of SMS.

TUFLOW FV ENGINE

The TUFLOW computational engine computes 2D hydraulic solutions. The engine uses a macro style text-file input which allows the user to flexibly and efficiently control model configurations and simulations.

For more information see the TUFLOW FV webpage.

SMS Interface

The TUFLOW FV engine is interfaced in SMS through the generic model interface.

TUFLOW FV Coverages

TUFLOW FV simulations require a boundary condition coverage and a materials coverage.

Boundary Conditions Coverage

The TUFLOW FV Assign Boundary Condition dialog

The TUFLOW FV boundary conditions coverage allows assigning boundary condition attributes to arcs drawn in the coverage. These attributes will then be assigned, or snapped, to the 2D mesh during the simulation run.

Attributes are assigned to arcs by right-clicking a selected arc and selecting the Assign BC command. This will open the Assign Boundary Condition dialog for TUFLOW FV.

The TUFLOW FV Assign Boundary Condition dialog has the following options:

BC Options – The BC Options tab has options for assigning attributes to the arc.

• Type – The option here determines what type of boundary condition will be assigned to the arc. The following types are available:
  • "Monitor" – Sets the arc to be a monitoring line.
  • "HQ (Head Discharge)" –
  • "Q (Nodestring Flow)"
  • "QN (Head Discharge)"
  • "WL (Water Level)"
  • "WLS (Sloping Water Level"
  • "WL_CURT (Water Level Curtain"
  • "ZG (Zero Gradient)"
• Subtype
• Define Curve
• Friction slope
• Dataset file
• Define Varaibles
• View Curve
• Define default
  • 'Q default
• Define offset
  • Q offset
• Define scale
  • Q scale
• Define update increment
  • Time
• Include mean sea level pressure

Materials

The TUFLOW FV materials coverage allows creating the polygons to hold the material attributes for the simulation run. The assigned material attributes will be mapped to the mesh/grid during the simulation run.

TUFLOW FV Simulation Menu

If the TUFLOW FV model paremeters have been correctly loaded into SMS, the TUFLOW FV menu is available when the Mesh module is active. The menu has the following commands:

• Check Mesh – Performs a general model check and will bring up the Model Checker dialog if errors are found.
• Define Model – Opens the model definitions. This is only accessible to the TUFLOW FV model developers.
• Global Parameters – Brings up the TUFLOW FV Global Parameters dialog where parameters for the model run are specified.
• Assign BC – Brings up the TUFLOW FV Nodestring Boundary Conditions dialog. Available when a boundary nodestring is selected.
• Material Properties – Brings up the TUFLOW FV Material Properties dialog.
• Run TUFLOW FV – Launches the TUFLOW FV model run.

Using the Model / Practical Notes

A TUFLOW licence is not required to run a TUFLOW FV model.
