    Mixed and Galerkin finite element approximation of flow in a linear viscoelastic porous medium

  • Original language description

    We propose two fully discrete mixed and Galerkin finite element approximation to a system of equations describing the slow flow of a slightly compressible single phase fluid in a viscoelastic porous medium. One of our schemes is the natural one for the backward Euler time discretization but, due to the viscoelasticity, seems to be stable only for small enough time steps. The other scheme contains a lagged term in the viscous stress and pressure evolution equations and this is enough to prove unconditional stability. For this lagged scheme we prove an optimal order a priori error estimate under ideal regularity assumptions and demonstrate the convergence rates by using a model problem with a manufactured solution. The model and numerical scheme that wepresent are a natural extension to 'poroviscoelasticity' of the poroelasticity equations and scheme studied by Philips and Wheeler in (for example) [Philip Joseph Philips, Mary F. Wheeler, Comput. Geosci. 11 (2007) 145 - 158] although - i
