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 ...

Solving the inverse Ising problem by mean-field methods in a clustered phase space with many states [PDF]
, 2016 In this work we explain how to properly use mean-field methods to solve the inverse Ising problem when the phase space is clustered, that is many states are present. The clustering of the phase space can occur for many reasons, e.g.

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

2-D PSTD simulation of optical phase conjugation for turbidity suppression [PDF]
, 2007 Turbidity Suppression via Optical Phase Conjugation (TS-OPC) is an optical phenomenon that uses the back propagation nature of optical phase conjugate light field to undo the effect of tissue scattering. We use the computationally efficient and accurate

A phase-field method for modeling cracks with frictional contact
, 2019 We introduce a phase-field method for continuous modeling of cracks with frictional contacts. Compared with standard discrete methods for frictional contacts, the phase-field method has two attractive features: (1) it can represent arbitrary crack ...

A Phase-Field Method for Interface-Tracking Simulation of Two-Phase Flows [PDF]
Progress in Multiphase Flow Research, 2005 For interface-tracking simulation of two-phase flows, we propose a new computational method, NS-PFM, combining Navier-Stokes (NS) equations with phase-field model (PFM). Based on the free energy theory, PFM describes an interface as a volumetric zone across which physical properties vary continuously.
