After many successful projects and new discoveries about brittle rock behavior, a new strain-softening model has been created. This new constitutive model is named IMASS (Itasca Model for Advanced Strain Softening). IMASS ( Ghazvinian et al., 2020) contains a two-mode softening of yield surfaces as shown in Figure 2.

· Geometric Data. FLAC3D organizes geometric data into sets, which are named collections of polygons, edges, and nodes. The data are topologically connected. Polygons are defined by a series of edges, and edges are defined by two nodes. The easiest way to create a geometric set is via the geometry import command. For example, the

Dynamic input is usually applied to the model boundaries with the zone face apply command. Accelerations, velocities, and forces can also be applied to interior gridpoints by using the zone gridpoint fix command. Note that the free-field boundary, shown in Figure 1, is not required if the only dynamic source is within the model (see Free-Field Boundaries).
