The GIS Mesher builds quality meshes for hydrodynamic models from GIS inputs leveraging your favorite GIS application.

Build Mesh from GIS

  • GIS spatial inputs
  • Generates hybrid quadrilateral/triangular meshes
  • Sizes at points or along polylines (perpendicular/parallel)
  • Breaklines to enforce features
  • Multiple layers for all GIS inputs for flexibility and ability to build mix and match features to create alternative meshes
  • Scale the mesh sizes globally or for specific layers
  • Elevations from a default value, GIS rasters, GIS polygons (override a specific area), or a combination of all
  • Mesh creation controlled by a text file which is flexible, reproducible, and scriptable
  • Includes a GUI to create a project, generate GIS files with correct fields, and to launch the mesher

Mesh generated with GIS Mesher standard tools

Solution Guided Meshing (SGM)

  • Guided automated meshing approach
  • Uses DEM to determine refinement on a finer scale than generated mesh
  • Iterative approach that uses FV solution to determine the sizing for the next mesh
  • The resulting mesh creation setup can be modified as desired
  • Depth change guided
    • Coarse cells in deep oceans or flat floodplains
    • Fine cells for channels or where elevation changing rapidly

TUFLOW FV Runner (Free no cost or registration)

  • Queue multiple simulations
  • Manage queue (change priority/remove/etc)
  • Run multiple models at once
  • Run on GPU, CPU or both
  • View screen output for running models
