A 3D fully-nonlinear potential-flow solver for efficient simulations of large-scale free-surface waves
Hanssen, Finn Christian W.; Helmers, Jens Bloch; Greco, Marilena; Shao, Yanlin (Journal article; Peer reviewed, 2022) -
An adaptive harmonic polynomial cell method with immersed boundaries: Accuracy, stability, and applications
Tong, Chao; Shao, Yanlin; Bingham, Harry; Hanssen, Finn Christian W. (Peer reviewed; Journal article, 2021)We present a 2D high-order and easily accessible immersed-boundary adaptive harmonic polynomial cell (IB-AHPC) method to solve fully nonlinear wave-structure interaction problems in marine hydrodynamics using potential-flow ... -
A Coupled Harmonic Polynomial Cell and Higher-Order Spectral Method for Nonlinear Wave Propagation
Hanssen, Finn Christian W.; Helmers, Jens Bloch; Greco, Marilena (Chapter, 2020)The present work deals with wave generation in fully nonlinear numerical wave tanks (NWT). As an alternative to modelling a moving (physical) wavemaker, a two-dimensional (2D) potential-flow NWT is coupled with an external ... -
Free-Surface Tracking in 2D with the Harmonic Polynomial Cell Method: Two Alternative Strategies
Hanssen, Finn Christian W.; Bardazzi, Andrea; Lugni, Claudio; Greco, Marilena (Journal article, 2017)Several cases of nonlinear-wave propagation are studied numerically in two dimensions within the framework of potential flow. The Laplace equation is solved with the Harmonic Polynomial cell (HPC) method, which is a field ... -
Local and Global Properties of the Harmonic Polynomial Cell Method: In-depth Analysis in Two Dimensions
Ma, Shaojun; Hanssen, Finn Christian W.; Siddiqui, Mohd Atif; Greco, Marilena; Faltinsen, Odd Magnus (Journal article, 2017)A detailed and systematic analysis is performed on the local and global properties of the recently developed Harmonic Polynomial Cell (HPC) method, a very accurate and efficient field solver for problems governed by the ... -
A Potential Flow Method Combining Immersed Boundaries and Overlapping Grids: Formulation, Validation and Verification
Hanssen, Finn Christian W.; Greco, Marilena (Peer reviewed; Journal article, 2021)A fully nonlinear two-dimensional numerical method based on potential-flow theory for water waves and their interaction with surface-piercing rigid bodies is presented. The harmonic polynomial cell (HPC) method is used to ... -
The harmonic polynomial cell method for moving bodies immersed in a Cartesian background grid
Hanssen, Finn Christian W.; Greco, Marilena; Shao, Yanlin (Chapter; Peer reviewed, 2015)In numerical simulations with moving bodies, and often with complex geometries, generation of high-quality body-fitted grids is a cumbersome and time-consuming task. An alternative is to use a fixed (Cartesian) background ...
