Abstract
AbstractWe investigated a space‐time Galerkin method applied to the dynamic analysis of fully‐saturated porous material. The governing set of equations are derived from the well‐studied Theory of Porous Media (TPM). The numerical scheme consists of a coupled finite element discretization in the space‐time domain. Discontinuous approximations of the primary variables in time are employed. A natural flux treatment is applied in time to impose the consistency between the adjacent time intervals. A simple space‐time decoupled adaptive strategy based on the “jumps” in time and the ZZ error indicator in space is investigated. Numerical experiments demonstrate the efficiency and reliability of the proposed approach. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
