Grid+ & CVLGrid

The Curvlinear Grid builder for EFDC

What is Grid+?

Grid+ is a new generation grid building tool. This new tool replaces our long-running grid building tool, CVLGrid . Grid+ has been designed to make the grid-building process quick, intuitive, and robust enough for even the most challenging waterbodies. It is fully integrated into EEMS and allows the user to move seamlessly between grid building and running models.

Build Complex Grids Quickly

Grid+ can be used to produce very complex grids (such as the Amazon River and the San Joaquin-Sacramento River Delta), and very large grids exceeding half a million cells.

Optimized for EE & EFDC

While our grid building tool may be used standalone, it has been optimized for use with EE and may be opened from within the EE GUI. This tool has been specifically designed for EFDC+ and allows the creation of model input files directly from the Grid+ interface. Moreover, unlike CVLGrid, Grid+ boasts online background maps, improved orthogonalization routines, and the ability to download online bathymetry data


Build Grids for Other Popular Models

EFDC+ and other hydrodynamic models such as ECOM, CH3D, and DELFT3D all require 2D curvilinear orthogonal or Cartesian grids.  Grid+ is the ideal tool to support the building of these grids quickly and effectively.
