Query: An Iterative Decoupled Algorithm with Unconditional Stability for Biot
  Model   This paper is concerned with numerical algorithms for Biot model. By
introducing an intermediate variable, the classical 2-field Biot model is
written into a 3-field formulation. Based on such a 3-field formulation, we
propose a coupled algorithm, some time-extrapolation based decoupled
algorithms, and an iterative decoupled algorithm. Our focus is the analysis of
the iterative decoupled algorithm. It is shown that the convergence of the
iterative decoupled algorithm requires no extra assumptions on physical
parameters or stabilization parameters. Numerical experiments are provided to
demonstrate the accuracy and efficiency of the proposed method.
