3D Domain Decomposition for Violent Wave-Ship Interactions
(Journal article, 2013)A 3D Domain-Decomposition (DD) strategy has been developed to deal with violent wave-ship interactions involving water-on-deck and slamming occurrence. It couples a linear potential flow seakeeping solver with a Navier–Stokes ... -
A 3D fully-nonlinear potential-flow solver for efficient simulations of large-scale free-surface waves
(Journal article; Peer reviewed, 2022) -
A domain-decomposition strategy for a compressible multi-phase flow interacting with a structure
(Journal article, 2014)The problem of a high-pressure gas cavity and its interaction with surrounding liquid and a close-by structure is examined numerically. Even though this is of interest in many practical applications, here, the focus is on ... -
An adaptive harmonic polynomial cell method with immersed boundaries: Accuracy, stability, and applications
(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 ... -
Free-Surface Tracking in 2D with the Harmonic Polynomial Cell Method: Two Alternative Strategies
(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 ... -
A high‐order harmonic polynomial method for solving the Laplace equation with complex boundaries and its application to free‐surface flows. Part I: Two‐dimensional cases
(Peer reviewed; Journal article, 2020)A high‐order harmonic polynomial method (HPM) is developed for solving the Laplace equation with complex boundaries. The “irregular cell” is proposed for the accurate discretization of the Laplace equation, where it is ... -
Local and Global Properties of the Harmonic Polynomial Cell Method: In-depth Analysis in Two Dimensions
(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 ... -
Non-proportional loading in sequentially linear analysis for 3D stress states
(Journal article; Peer reviewed, 2019)Sequentially linear analysis (SLA), a non‐incremental‐iterative approach towards finite element simulation of quasi‐brittle materials, is based on sequentially identifying a critical integration point in the model, to ... -
Two solution strategies to improve the computational performance of sequentially linear analysis for quasi‐brittle structures
(Peer reviewed; Journal article, 2020)Sequentially linear analysis (SLA), an event‐by‐event procedure for finite element (FE) simulation of quasi‐brittle materials, is based on sequentially identifying a critical integration point in the FE model, to reduce ...
