论文摘要
我们优化了固化的相位场晶体（PFC）模型的数值时间稳定常规。通过数值实验，我们证明了我们的方法可以提高基础时间集成方案的准确性，从而提高了几个数量级。我们研究了不同的时间集成方案。此外，作为应用程序的原型示例，我们将数值方法扩展到具有明确温度耦合的PFC固化模型。
We optimize a numerical time-stabilization routine for the phase-field crystal (PFC) models of solidification. By numerical experiments, we showcase that our approach can improve the accuracy of underlying time integration schemes by a few orders of magnitude. We investigate different time integration schemes. Moreover, as a prototypical example for applications, we extend our numerical approach to a PFC model of solidification with an explicit temperature coupling.
