pypfc 0.0.4

A Python Package for Phase Field Crystal (PFC) Simulations

A Python package for GPU-accelerated 3D Phase Field Crystal simulations

Overview

pyPFC is a high-performance simulation framework designed for modeling crystal structures and their evolution using the Phase Field Crystal (PFC) method. The code uses PyTorch to allow execution on both CPUs and GPUs, with particularly efficiency gained on GPU platforms. pyPFC is developed with a combined focus on computational efficiency, flexibility and accessibility, making it suitable for both research and educational purposes.

Installation instructions, examples and API documentation can be found in the pyPFC documentation.
