A boundary-penalized isogeometric analysis for second-order hyperbolic equations
Journal of Computational Science, 2022 Explicit time-marching schemes are popular for solving time-dependent partial differential equations; one of the biggest challenges these methods suffer is increasing the critical time-marching step size that guarantees numerical stability. In general, there are two ways to increase the critical step size.
