![]() To perform the MPF simulation on an NVIDIA GPU, the program code is developed in CUDA Fortran. This is an important phenomenon for predicting the morphology of multiphase microstructures in steel. In this paper, we use a graphics processing unit (GPU) to accelerate the two-dimensional MPF simulation of austenite-to-ferrite transformation in a Fe-C alloy. ![]() However, because we need to solve the time evolution equations for multiple-order parameters derived from the total Gibbs free energy, MPF simulations are very computationally expensive. ![]() ![]() The multiphase field (MPF) method is recognized as a powerful numerical method to simulate microstructural evolutions, such as solidification, grain growth, recrystallization, and phase transformation, in various materials. ![]()
