MODFLOW Evaluations

This feature is only available with the Hydrogeology extension.

When a MODFLOW model is exported, the evaluated geological model is used to assign lithologies to the cells in the grid. If the grid has not been evaluated against a geological model, you must do so before you can edit the hydrological properties and before you can export the grid.

To evaluate a MODFLOW model, right-click on the model in the project tree and select Evaluations. Although you can evaluate an interpolant or distance function, they cannot be exported with the grid and are simply used for displaying the grid in Leapfrog Geo.

A window will appear listing all objects in the project that can be used for an evaluation. Once you have selected one or more objects, click OK. You will then be able to select the evaluations from the view list, as described in Evaluations.

Assigning an Evaluation for Export

For MODFLOW models created in Leapfrog Geo, the evaluation used when creating the model will automatically be assigned as the evaluation for export. A hydrological properties table () will appear in the project tree as part of the model.

If the model was imported into Leapfrog Geo or created without being evaluated against a geological model, you will need to manually set the evaluation for export. To do this:

Evaluate the grid against one or more geological models, as described above.
Right-click on the model in the project tree and select Set Evaluation for Export. The Select Evaluation window will appear showing all geological models evaluated on the grid. Select the required evaluation and click OK.

A hydrological properties table will be added to the model in the project tree. Edit hydrological properties by double-clicking on the table. See MODFLOW Hydrological Properties.
