The Curvlinear Grid builder for EFDC
Build Complex Grids Quickly
CVLGrid is frequently used to produce very complex grids, such as Amazon River, the San Joaquin-Sacramento River Delta, and very large grids, exceeding half a million cells. Watch this video to see how to build a grid of the waterbodies around Manhattan Island (Hudson River, Harlem River, and East River) in minutes.
Optimized for EE & EFDC
Our grid building tool has been optimized for use with EFDC+, EFDC_EPA, and EFDC_Hydro.
Users can create the EFDC input files directly from CVLGrid.
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. CVLGrid has been designed as a tool to support the building of these grids quickly and effectively.
