Computers & Mathematics with Applications, 2017•ElsevierA novel mixed formulation of the Biot equations of poroelasticity is proposed motivated by an
application in the biomechanics of edema formation in intestinal tissue. The mixed
formulation is discretized by two variants of the primal discontinuous Galerkin method in
conjunction with a backward Euler timestepping. An a-priori error analysis for the symmetric
and non-symmetric establishes rates of convergence in the L 2 and energy norms.
Convergence of the scheme is further investigated numerically.
