This Load EFDC Grid option allows the user to load a grid of an existing EFDC model. This browsing window is shown in Figure 1. After clicking the OK button the EFDC Grid is loaded in Figure 2.

The "Scale" input box allows the user to apply a conversion factor to the centroid units used in the legacy LXLY file. The EFDC_Explorer default X, Y unit is meters. Many applications use kilometers or miles as the units for the cell centroids provided in the LXLY file. To correctly display the model these cell centroid coordinates must be converted to meters. CVLGrid can perform this function by entering the conversion factor in the Scale box when loading the model for the first time. Note: When a model is loaded and then viewed but looks like a cluster of large cells stacked on top of one another, it is likely to be a LXLY units conversion issue. Try reloading the model with an appropriate scale factor.
The "Don't use the IJ Map to compute nodal coordinates" box will force CVLGrid to search through all the cell corners to build the nodes
