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

摘要

We set up a computational tool to numerically model static and quasi-static deformation generated by faultingsources embedded in plane or spherical domains. We use a Finite Element (FE) approach to automatically implementarbitrary faulting sources and calculate displacement and stress fields induced by slip on the fault. Thepackage 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.
