Figure 7: Numerical application used to illustrate the computational efficiency of the proposed algorithm: (a) geometry of a fluid-filled borehole with a null-thickness empty crack in its vicinity and position of the blast load; (b) boundary elements used by the BEM/TBEM model; (c) position of virtual loads and collocation points used by the MFS model; (d) position of virtual loads, collocation points (MFS), and boundary elements (TBEM) used by the proposed MFS/TBEM coupling formulation.
