A edge-based three-dimensional interface element for simulation of joints,
faults and other discontinuities present in several geomechanical applications
is proposed. Edge-based data structures are used to improve computational
efficiency of Inexact Newton methods for solving finite element nonlinear
problems on unstructured meshes. Numerical experiments in the solution of
three-dimensional problems in cache based and vector processors have shown
that memory and computer time are reduced.
