FLAC

FLAC

FLAC is a two-dimensional explicit finite difference program for engineering mechanics computation. This program simulates the behavior of structures built of soil, rock or other materials that may undergo plastic flow when their yield limits are reached. 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 modeled.

Highlighted Features

  • Large-strain simulation of continua, with optional interfaces that simulate distinct planes along which slip and/or separation can occur
  • Explicit solution scheme, giving stable solutions to unstable physical processes
  • Groundwater flow, with full coupling to mechanical calculation (including negative pore pressure, unsaturated flow, and phreatic surface calculation)
  • Convenient specification of general boundary conditions
  • Structural elements (including non-linear material behavior), with general coupling to the continuum
