Generate New Model

EFDC_Explorer can generate a new grid and write to disk the essential EFDC model files to begin building an application. Figure 1 shows an example model generation options form.
There are many settings that need to be assigned when building a new model. The approach taken by EFDC_Explorer is to use a master input file for EFDC which is stored in a non-editable database. EFDC_Explorer automatically updates the EFDC default initial conditions from this MS Access file (EFDC.MDB) for the following files:

• EFDC.INP
• WQ3DWC.INP
• WQ3DSD.INP
• WQRPEM.INP

From EE7.3 onward this method supersedes the use of the EFDC.INP file which had been used to update the basic features the user required such as computation options, hydrodynamic settings, and a range of miscellaneous settings. Formerly a valid EFDC.INP had to be selected prior to being able to generate a new model.

EFDC_Explorer can quickly generate simple to complex Cartesian grids. These grids can be uniform or expanding, rotated and trimmed to match the physical domain. For more complex grids, EFDC_Explorer can import grids generated with many tools or other models as described further below. In addition to these grid generation/import options, EFDC_Explorer can import a generic set of nodal points.
