The phase field method was first introduced to model solid–liquid phase transition in which surface tension and nonequilibrium thermodynamics behaviour become important at the interface. Computationally, the phase field method has features in common with the level set method (Chen et al., 1991; Eva...
The paper is organized as follows: first, we highlight the method and the governing equations, followed by an introduction to the phase-field method. We then explain the numerical approach, including the coupling process. We test and verify this workflow in several case studies to demonstrate it...

The phase-field (PF) method is a physics-based computational approach for simulating interfacial morphology. It has been used to model powder melting, rapid solidification, and grain structure evolution in metal additive manufacturing (AM). However, trad
PRISMS-PF is a powerful, massively parallel finite element code for conducting phase field and other related simulations of microstructural evolution. The phase field method is commonly used for predicting the evolution if microstructures under a wide range of conditions and material systems. PRISMS-PF...
This section briefly introduces the two methods, peridynamics (PD) and phase field (PF), respectively. A brief overview of the governing equations, material models, discretizations, numerical analysis, and advanced visualization methods is given. We introduce the ingredients for the comparison of these...
For the velocity field, four boundary conditions are specified as “noSlip”. All other parameters remain at their default values. 4. Results To validate the feasibility of the three-dimensional model, we processed the generated grid information using Python to obtain the visualization of the ...
