IWFM Mesh Generator
(Released: November 8, 2021) This is a mesh generator that is integrated into ESRI's ArcMap software, version 10.8.x. It utilizes shapefiles to define model boundary, streams, enforcement lines, holes and wells to generate a triangular, quarilateral or mixed triangular-quadrilateral finite element mesh. It uses Triangle, developed by Dr. Jonathan Richard Shewchuk, and Gmsh, developed by Christophe Geuzaine and Jean-François Remacle, as the mesh generator engines. The mesh can be converted to a shapefile to perform various data analysis to develop input data (e.g. soil properties, land use distribution, development of stratigraphic layers) for IWFM applications. Groundwater and stream nodes as well as finite elements can be numbered automatically and the IWFM mesh files can be exported to text files. After downloading the ESRI add-in installation file (MeshGenerator.esriAddin), double-click on it and follow the instructions. After installation, start ArcMap and click the "IWFM Mesh Generator" button.
