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
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
