    This study presents Nalu-Acoustics, a GPU-accelerated high-order finite-difference solver for acoustic propagation analysis over large domains. The solver employs dispersion-relation-preserving (DRP) spatial discretization and low-dissipation low-dispersion Runge–Kutta (LDDRK) time integration to minimize numerical dispersion and dissipation. Perfectly matched layers (PML) are applied at...

    The time-explicit discontinuous Galerkin finite element framework has been a powerful tool used for modelling of acoustic wave propagation in the time domain. Its applications stretch from room and underwater acoustics to medical and non-destructive inspection ultrasound and can be based on acoustic waves of small and finite amplitudes. The effective simulation of acoustic propagation in...

    Vibrational fatigue is a leading cause of pipeline failure in industrial facilities, yet accurately predicting it remains a significant engineering challenge due to the complex interplay among structural dynamics, fluid-induced loading, and geometric nonlinearities. This work presents a numerical procedure to estimate the vibrational fatigue of piping systems subjected to dynamic excitation in...

    Computationally-efficient single-frequency acoustic solvers have many applications. Our interest is in therapeutic and diagnostic biomedical ultrasound. I will describe recent work on a class of numerical acoustic models of wave propagation through heterogeneous soft tissue media based on unconditionally convergent Neumann series, made efficient through the use of the Fast Fourier Transform....
