Selected issues of phase-field crystal simulations

The European Physical Journal Plus, 2011
In this contribution our focus is on the phase-field crystal method, which can be viewed as the youngest methodology in the field of interface computation based on recent work by Elder et al. (Phys. Rev. Lett. 88, 245701 (2002)). It bridges the gap between the molecular simulation approaches and the phase-field approach by operating on diffusive time ...

Phase Field Simulation of Solidified Multiple Grains

Advanced Materials Research, 2012
A phase-field model based on the Ginzburg-Landan theory and KKS model is used to simulate the dendrite growth of multiple grains for Al-Cu alloy. The influence of solidification latent heat and undercooling on the growth of equiaxed dendrite, solute distribution and temperature distribution were studied.

Phase Field Simulation of Ferroelectric Single Crystals

Aerospace, 2005
Ferroelectric materials exhibit spontaneous polarization and domain structures below the Curie temperature. In this study a cubic to tetragonal phase transformation and the evolution of domain structures in ferroelectric crystals are simulated by using the time-dependent Ginzburg-Landau equation.

Phase field simulations of ferroelectric materials

2014
Ferroelectric materials have become preferred materials in a wide variety of electronic and mechatronic devices due to their pronounced dielectric, piezoelectric, and pyroelectric properties. The material macroscopic properties are related to the microscopic domain structure of the materials.

Isogeometric Phase-Field Simulation of Boiling

2016
In this work we consider the Navier–Stokes–Korteweg equations, a diffuse-interface model describing liquid–vapor phase transitions. A numerical scheme for this model is constructed based on functional entropy variables and a new time integration concept.

Accelerating Phase-Field Simulations for HPC-Systems

2021
In the last decades simulations have become a powerful tool to understand physical processes and accelerate the development of new products. A high computational effort is necessary to resolve these processes accurately with quantitative models. Especially for large-scale and massive parallel simulations a reduction of the total computational time ...

Multi-phase-field simulations for dynamic recrystallization

Computational Materials Science, 2009
Abstract A dynamic recrystallization multi-phase-field (MPF-DRX) model that can approximately take into account grain deformation during dynamic recrystallization (DRX) has been developed, where the grain deformation was introduced by changing the size of a finite difference grid so as to keep the volume constant.
