The material can yield and flow, and the grid can deform in small and large-strain mode and move with the material that is represented. Each element behaves according to a prescribed linear or non-linear stress/strain law in response to the applied forces or boundary restraints.

Materials are represented by elements, or zones, which form a grid that is adjusted by the user to fit the shape of the object to be modelled. The two programmes simulate the behaviour of soils, structures built on soil, rock or other materials that may undergone plastic flow when their yield limits are reached. FLAC Version 3.3 is a two-dimensional explicit finite difference program for solving mining and geotechnical engineering problems.
