How to Create an Hybrid Mesh by Combining BlockRanger and Griddle

Among the different meshing solutions available today, hybrid meshes obtained by mixing several meshing tools represent a flexible way to obtain accurate results in civil engineering models, where both geometrical complexities and the need of a structured mesh are playing an important role.

The webinar shows how to generate a FLAC3D hybrid mesh of a tunnel system consisting of three tunnels intersecting each other by combining the use of BlockRanger and Griddle. The advantages of this type of mesh is discussed by illustrating a coupled hydro-mechanical simulation of the tunnel excavations.
