In Leapfrog Geo, creating a 3D FEFLOW model requires:
- A geological model that will be used to assign lithologies to the FEFLOW model’s blocks.
- A 2D grid that defines the block size, boundaries and surface features.
Steps for creating a 3D FEFLOW model that can be exported and run outside Leapfrog Geo are:
1. Create a geological model.
2. Create and refine a 2D model in Leapfrog Geo or import a FEFLOW model.
3. Create the 3D model from the 2D model or another 3D model in the project.
4. Evaluate the new 3D model against a geological model.
5. Edit the material types.
6. Export the 3D FEFLOW model.
Once the model has been processed outside of Leapfrog Geo, a results file can be saved that can be imported into Leapfrog Geo and visualised in the scene.
A 2D grid can be created in or imported into Leapfrog Geo. A 3D grid can also be used, in which case the layer information is not used in creating the 3D grid. Creating the 2D grid in Leapfrog Geo provides the most flexibility, as the block sizes can easily be changed, the boundaries modified and features added to provide finer resolution where there is more data available.
You can also import FEFLOW problem files and result files, visualise them in Leapfrog Geo and use them as the basis for new models. See Importing a FEFLOW Grid.
See FEFLOW Model Display for information on options for displaying FEFLOW models in the scene.
3D grids created in Leapfrog Geo can be evaluated against a geological model when they are created. Grids imported into Leapfrog Geo or that were not evaluated when they were created can be evaluated as described in FEFLOW Evaluations.
