Implementation and verification of an explicit overset grid method [PDF]
, 2018 This paper presents an initial implementation of the overset method in the solver ReFRESCO. The DCI (Domain Connectivity Information) is computed by the external library Suggar++ and the coupling between meshes is done explicitly. Manufactured solutions and analytical solutions are used in order to quantitatively assess the discretisation errors.

Numerical study on the 6-DOF motions of ship turning in waves [PDF]
Scientific ReportsShips are often disturbed by waves when they are sailing on sea, and the influence is usually not negligible. When a ship is manoeuvering in waves, the wave will seriously threaten the ship’s navigation safety.

On the need for higher order interpolation with overset grid methods [PDF]
, 2019 Overset methods, by overlapping several grids, allow large and arbitrary motion of bodies. First developed for the aerospace industry (Benek et al., 1985), it is now used for a wider range of applications like maritime ones (Carrica et al., 2013). At the fringes of each grid, the coupling is done by interpolating field variables.

Hermite-Discontinuous Galerkin Overset Grid Methods for the Scalar Wave Equation [PDF]
Communications on Applied Mathematics and Computation, 2020 We present high order accurate numerical methods for the wave equation that combines efficient Hermite methods with eometrically flexible discontinuous Galerkin methods by using overset grids. Near boundaries we use thin boundary fitted curvilinear grids and in the volume we use Cartesian grids so that the computational complexity of the solvers ...
