These features are only available as part of the Hydrogeology module. See Flow Modelling for more information.
Once you have created a geological model, you can use it as the basis for a ModFlow model. You can also import existing ModFlow models and assign lithologies from a geological model.
Steps for creating a ModFlow model that can be exported and run outside Leapfrog Geo are:
1. Create a geological model.
2. Create the ModFlow model using the geological model to set the grid spacing and layers.
3. Evaluate the new model against a geological model, if it wasn’t when it was created.
4. Edit the hydrological properties.
5. Export the ModFlow model to ModFlow or Groundwater Vistas.
Once the model has been processed outside of Leapfrog Geo, the model can be imported into Leapfrog Geo and visualised in the scene.
Creating ModFlow models in Leapfrog Geo has the advantage that the resolution can be easily changed and the properties of the grid can be made to honour boundaries defined in geological models. See Creating a ModFlow Model.
See ModFlow Model Display for information on options for displaying models in the scene.
Models created in Leapfrog Geo can be evaluated against a geological model when they are created. Models imported into Leapfrog Geo or that were not evaluated when they were created can be evaluated as described in ModFlow Evaluations.
Once a model has been defined and evaluated against a geological model, hydrological properties can be assigned and the grid can be exported. See ModFlow Hydrological Properties and ModFlow Model Export.
