EFDC_Explorer (EE) allows you to rapidly generate Cartesian grids or import of grids from a wide range of 3rd party tools and alternative modeling systems. This allows you to quickly build and modify grids for use in EEMS models.
CVLGrid, EEMS’s curvilinear orthogonal grid generation tool, has been intentionally designed to create and edit grids for EFDC+, though it also works with any other 2D modeling tools that utilize curvilinear grids.
EEMS has been optimized to import CVLGrid files and quickly generate an EFDC+ model.
Create Cartesian Grids
EE generates Cartesian grids with either uniform grid spacing or variable grid spacing. A rectangular model domain can be easily generated by defining the domain extents and grid interval. A more complex model domain can be specified within EE by use of a shoreline file. EE allows you to quickly and easily generate models enabling rapid grid resolution testing during the early stages of model development.
Import 3rd Party Grids
EE has been designed to import complex curvilinear models generated by third party utilities such as Delft RGFGrid formatted files (i.e. GRD file), Grid95, SEAGrid, as well as any generic cell based nodal coordinate files. This helps users leverage existing work that has already been done on their project.
Import Other Model Grids
EE allows you to quickly import grids from a wide variety of different hydrodynamic models such as CH3D-WES, CH3D-IMS, ECOMSED, and prior versions of EFDC. EE also imports grids with multiple sub-domains.
EE also imports grids with multiple disconnected sub-domains which can be connected using the EFDC+ N/S and/or E/W cell connections.
