Rising water software is the developer of the GIS Mesher software. The GIS Mesher builds meshes for hydrodynamic models such as TUFLOW FV that use a combination of quadrilateral and triangular meshes. Spatial data is provided to the mesher as GIS layers. Use your favorite GIS application to build quality meshes quickly and easily. Solution guided meshing uses results from initial mesh solutions to iteratively improve meshes. Making it easy to generate good meshes for even complicated hydrodynamics. Free (no cost or registration) flexible TUFLOW FV runner that can manage running multiple simulations concurrently and supports both CPU and GPU simulations.
