General Program Operation
Upon starting EFDC_Explorer the user will be presented with the form shown in Figure 2-1.
This form is basically divided into three parts. At the top of the form, the main Toolbar is shown
providing quick access to many of the primary EFDC_Explorer features and actions. The main
form is then divided into two primary sections. The upper section represents the pre-processor
functions and the lower section provides access to some of the post processor functions. The
operation and further instructions for each of these groupings will be described in the following
sections.

EFDC_Explorer Files
The main control file for every EFDC application is the EFDC.INP file. EFDC.INP is an ASCII
file structured into card groups that generally have the same basic objective, e.g. card group 8
(C8) contains the settings for the run time but it also contains other miscellaneous parameters.
This file contains almost all of the computational options and data settings.
The EFDC model uses fixed file names (e.g. DXDY.INP) based on the type of information each
file contains. The files that are required for a model application vary based on the
computational and grid options selected. For example, if the ISVEG flag (C5) is >0 then the
VEGE.INP file, which contains vegetation information to compute vegetation based flow
resistance, must be supplied. EFDC_Explorer reads and writes these same files and reduces
the need for the user to remember exactly which file and/or which card group has what flag or
setting.
EFDC_Explorer requires additional information and data to perform its pre-processing and
visualizations. When saving an existing or new project, EFDC_Explorer automatically
generates these files based on the project’s settings. The following provides a list of
EFDC_Explorer specific files and their functions:
EFDC.DS
This is the main EFDC_Explorer project file. This file contains
much of the labeling, formatting, boundary condition, and modeldata linkage information. This file is REQUIRED for
EFDC_Explorer to correctly manage boundary groups
CORNERS.INP
This file contains the corner coordinates for each cell.
EFDC_Explorer computes these using the cell center coordinates,
DX, DY and cell rotation. It then matches the cell corners and
builds the nodal list. By default, EFDC_Explorer displays the 2D
plan view cells using these corner coordinates. However, the user
can choose to view the rectangular cells if desired.
EFDC_LOG.DS
This file contains the run log that is displayed in the main
EFDC_Explorer form. This file is ASCII and can be viewed with
any ASCII editor.
CalForm_TS.DS
This file contains formatting and labeling information for the time
series calibration plots.
CalForm_VP.DS
This file contains formatting and labeling information for the
vertical profile calibration plots.
