FEMSA: a finite element simulation tool for quasi-static seismic deformation modeling

M. Volpe, D. Melini, A. Piersanti

Abstract


We set up a computational tool to numerically model static and quasi-static deformation generated by faulting
sources embedded in plane or spherical domains. We use a Finite Element (FE) approach to automatically implement
arbitrary faulting sources and calculate displacement and stress fields induced by slip on the fault. The
package makes use of the capabilities of CalculiX, a non commercial FE software designed to solve field problems
(see for details), and is freely distributed by request.
