Grid+ is integrated with EFDC+ Explorer. This option allows us to modify the model grid of the current model while opening it. Notice that the Grid+ version launched from EE has features that are limited compared to the stand-alone Grid+ version in EEMS. It does not allow changing the number of grid cells. It is used to improve grid orthogonalization or change grid nodes.
To launch the Grid+ while opening a model in EE, click the Tools menu to extend options, select Edit Grid with Grid+ option, as shown in Figure 1.
