Query: Energy Stability and Convergence of SAV Block-centered Finite Difference
  Method for Gradient Flows   We present in this paper construction and analysis of a block-centered finite
difference method for the spatial discretization of the scalar auxiliary
variable Crank-Nicolson scheme (SAV/CN-BCFD) for gradient flows, and show
rigorously that scheme is second-order in both time and space in various
discrete norms. When equipped with an adaptive time strategy, the SAV/CN-BCFD
scheme is accurate and extremely efficient. Numerical experiments on typical
Allen-Cahn and Cahn-Hilliard equations are presented to verify our theoretical
results and to show the robustness and accuracy of the SAV/CN-BCFD scheme.
