Examples of the two fault triggering methods, fault insertion (a), (c) and fault seeding (b) and (d). Figures (a) and (b) show undeformed geometries with the initial conditions at fault location. Note that the fault path in (a) is used to split the continuous geometry at early stages of the simulation. Figures (c) and (d) show the model mesh after the first deformational stage of the simulation.
