Engineering Reports, Volume 7, Issue 4, April 2025.Three‐dimensional field of wave elevation over a paraboloidal shoal near a wall. ABSTRACT This paper suggests an exact boundary condition, so‐called Neumann‐to‐Dirichlet (NtD) boundary condition for numerical analysis of the three‐dimensional wave motion over piecewise smooth topographies near a vertical breakwater.

International Journal for Numerical Methods in Fluids, Volume 97, Issue 4, Page 462-483, April 2025.We investigate the macro‐element hybridized discontinuous Galerkin (HDG) method that combines advantages of continuous and discontinuous finite elements for compressible flow analysis. To efficiently handle large systems, we focus on computational strategies at the level of the direct local solver and the matrix‐free iterative global solver.

Investigation of parabolic computational techniques for internal high-speed viscous flows [PDF]
A feasibility study was conducted to assess the applicability of an existing parabolic analysis (ADD-Axisymmetric Diffuser Duct), developed previously for subsonic viscous internal flows, to mixed supersonic/subsonic flows with heat addition simulating a

Shock-resolved Navier–Stokes simulation of the Richtmyer–Meshkov instability start-up at a light–heavy interface [PDF]
, 2010 The single-mode Richtmyer–Meshkov instability is investigated using a first-order perturbation of the two-dimensional Navier–Stokes equations about a one-dimensional unsteady shock-resolved base flow. A feature-tracking local refinement scheme is used to
