“…Instead of providing cumulative
error estimates or rough
error estimates for pressure
[7,10], our research presents rigorous
error estimates of pressure at the final time, drawing inspiration from
[16,23]. Furthermore, the unconditional convergence of Method 2 suggests that such a second order method can also be applied to iterative schemes for Biot's model
[3,4,11], significantly enhancing computational efficiency. We comment here that the theoretical framework in this work can be extended to provide a novel perspective for analyzing decoupled schemes
[14,17] that offer high efficiency and superconvergence.…”
