Bernaise: A Flexible Framework for Simulating Two-Phase Electrohydrodynamic Flows in Complex Domains
Frontiers in Physics, 2019 Bernaise (Binary Electrohydrodynamic Solver) is a flexible high-level finite element solver of two-phase electrohydrodynamic flow in complex geometries. Two-phase flow with electrolytes is relevant across a broad range of systems and scales, from “lab-on-

High resolution digital holographic synthetic aperture applied to deformation measurement and extended depth of field method [PDF]
, 2010 This paper discusses the potential of the synthetic-aperture method in digital holography to increase the resolution, to perform high accuracy deformation measurement, and to obtain a three-dimensional topology map.

Phase Field Methods for Binary Recovery [PDF]
, 2014 We consider the inverse problem of recovering a binary function from blurred and noisy data. Such problems arise in many applications, for example image processing and optimal control of PDEs. Our formulation is based on the Mumford-Shah model, but with a phase field approximation to the perimeter regularisation.

Phase-field method for epitaxial kinetics on surfaces [PDF]
The Journal of Chemical Physics, 2018 We present a procedure for simulating epitaxial growth based on the phase-field method. We consider a basic model in which growth is initiated by a flux of atoms onto a heated surface. The deposited atoms diffuse in the presence of this flux and eventually collide to form islands which grow and decay by the attachment and detachment of migrating atoms ...

A mesoscale numerical approach to predict damage behavior in concrete basing on phase field method
Vietnam Journal of Mechanics, 2021 In this paper, we develop a numerical approach to simulate the 2D complex damage and fracture process of quasi-brittle concrete materials. Based on the phase field theory for the case of elastic isotropic multicomponent materials and the generation ...

A practical phase field method for an elliptic surface PDE [PDF]
IMA Journal of Numerical Analysis, 2020 Abstract We consider a diffuse interface approach for solving an elliptic PDE on a given closed hypersurface. The method is based on a (bulk) finite element scheme employing numerical quadrature for the phase field function and hence is very easy to implement compared to other approaches.

Fourier-Spectral Method for the Phase-Field Equations
Mathematics, 2020 In this paper, we review the Fourier-spectral method for some phase-field models: Allen–Cahn (AC), Cahn–Hilliard (CH), Swift–Hohenberg (SH), phase-field crystal (PFC), and molecular beam epitaxy (MBE) growth.

Accelerating fracture simulation with phase field methods based on Drucker-Prager criterion
Frontiers in Physics, 2023 The paper presents a framework for accelerating the phase field modeling of compressive failure of rocks. In this study, the Drucker-Prager failure surface is taken into account in the phase field model to characterize the tension-compression asymmetry ...

A Fully Coupled Thermomechanical Phase Field Method for Modeling Cracks with Frictional Contact
Mathematics, 2022 In this paper, a thermomechanical coupled phase field method is developed to model cracks with frictional contact. Compared to discrete methods, the phase field method can represent arbitrary crack geometry without an explicit representation of the crack
