Jun 27, 2023 · Solve a phase-field (Allen-Cahn) problem in one-dimension. To run this example from the base FiPy directory, type python examples/phase/simple/input.py at the command line. A viewer object should appear and, after being prompted to step through the different examples, the word finished in the terminal.

Python implementation of phase field model using Fourier Spectral Methods from the book Programming Phase-Field Modeling originally written in MATLAB. It is shown a case study of the numerical implementation of the semi-implicit Fourier spectral algorithm for the solution of the conserved Cahn-Hilliard equation in phase-field modeling.

Mar 24, 2025 · The PhaseFieldX project is designed to simulate and analyze material behavior using phase-field models, which provide a continuous approximation of interfaces, phase boundaries, and discontinuities such as cracks.

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 …

Jun 27, 2023 · Solve a phase-field (Allen-Cahn) problem in one-dimension. examples.phase.binaryCoupled Simultaneously solve a phase-field evolution and solute diffusion problem in one-dimension.

Dec 22, 2024 · Phase-field modeling is a computational technique widely used in materials science, physics, and engineering to study the evolution of microstructures during processes like phase transformations, grain growth, and solidification.

I have selected three models and the Jupyter Notebook format to let the learner focus on the important aspects of phase field modeling and to provide an interactive, flexible form of instruction. Please let me know if you find it useful.

Mar 15, 2010 · Solidification Phase Field Modeling. What to expect Once the concept of conserved and non-conserved order parameters have been defined, the concept of phase field is introduced to construct the simplest model to describe a phase transformation (liquid--solid).

In this series of demos, we show how to implement simple phase field models using finite differences. We implement examples from the book Programming Phase-Field Modelling by S. Bulent Biner. Specifically, the model for spinodal decomposition implemented in this notebook can be found in Section 4.4 of the book.
