GeoFEST 4.8 - Finite Element Model Software

GeoFEST uses stress-displacement finite elements to model stress and flow in a realistic model of the Earth's crust and upper mantle in a complex region such as the Los Angeles Basin. The model includes stress and strain due to the elastic response to an earthquake event in the region of the slipping fault, the time-dependent viscoelastic relaxation, and the net effects from a series of earthquakes. The physical domain may be two or three dimensional and may contain heterogeneous materials and an arbitrary network of faults.

The program source is written in C, and is targeted to be compiled and run on UNIX systems, and on diverse UNIX derivatives including LINUX, HPUX, and SunOS.

GeoFEST requires a no-cost license and can be downloaded from the OpenChannel Foundation.

GeoFEST 4.8 is now effective and convenient for performing regional simulations of earthquake stress transfer, deformation, and strain from immediate earthquake response, post-event relaxation and fault afterslip, and multiple-earthquake cycles. By making use of Pyramid library features to automatically perform parallel mesh refinement to drive the refinement by subdivision of those regions of the mesh most in need of increased accuracy. The application is much easier to set up and run for large, accurate simulations.
