FLAC3D Theory and Background

This section contains background information and descriptions of the theoretical basis for the basic components of FLAC3D. It is composed of five major sections, described as follows.

The theoretical formulation for FLAC3D is described in the first section, Theoretical Background. This includes an overview of the explicit finite difference method and the numerical implementation in FLAC3D.

The next section, Interfaces, describes the FLAC3D interface logic. It includes several example applications. Interfaces represent planes on which sliding and separation can occur.

The last section describes the implementation of Fluid-Mechanical Interaction in FLAC3D models, with illustrative examples.
