This training is an introduction to continuous modeling with FLAC2D and FLAC3D. At the end of the course, participants will master the graphical interface, documentation and the main modeling steps. Concepts are illustrated using a tunnel excavation example, from building the model geometry to results analysis. This introductory course provides the foundation for more advanced use of the software, which can be covered in more specific training modules.
GExtrude quickly creates a watertight modeling domain from a given surface mesh (e.g., a topography, meshed surface scans, etc.) This is done by extruding a surface mesh to a bounding surface with any orientation. There are options to create structured or unstructured mesh for the extruded parts and to keep the extruded parts separate or merged with the original mesh.
Note that the new mesh (domain mesh) is not automatically intersected with any other meshes (except for the initial extruded mesh) and, therefore mesh intersection (GInt) and remeshing operations (GSurf) may be needed.
