May accelerate cardiac model simulations; leaves open validation before clinical workflow integration.
The proposed ADI schemes efficiently solve the nonlinear cardiac monodomain model, reducing computational time and memory while maintaining second-order accuracy.
Belhamadia et al. (2020) studied Cardiac monodomain model (computational simulation). Operator-splitting alternating direction implicit (ADI) schemes vs. Standard semi-implicit Crank-Nicolson/Adams-Bashforth method was evaluated on Computational time and memory consumed. Operator-splitting alternating direction implicit (ADI) schemes achieved second-order accuracy in space and time while reducing computational time and memory compared to standard numerical methods.
