Due to the involvement of “phased field”, phase-field method can be essentially treated a multifield problem even for pure mechanical problem. Therefore, it is supposed that the implementation of PFM based on a software developer that especially supports the solution of multifield problems should...
Rechargeable batteries have a profound impact on our daily life so that it is urgent to capture the physical and chemical fundamentals affecting the operation and lifetime. The phase-field method is a powerful computational approach to describe and predi
Linking phase-field modeling methods to commercial thermodynamic software tools has been pursued aggressively in recent years, which can enable multi-component alloy systems to be simulated. In addition to establishing an appropriate computational method that captures the range of potential mechanisms, and...
Programming Phase-Field Modeling provides a fast-track pathway to numerical implementation of phase-field modeling—a relatively new paradigm that has become the method of choice for modeling and simulation of microstructure evolution in materials. It se
A CVM-based phase field method has been also developed to study microstructure evolution in alloys10,11. In this method the alloy composition was kept fixed and the order–disorder phase transformation was treated at different temperatures. However, this method cannot discuss the entire phase ...
Compared with the traditional interface-capturing method, the phase-field model has a firm physical basis because it is based on the Ginzburg–Landau theory and conserves mass and energy. It also performs well in two-phase flow at the large density ratio. However, the high-order differential ...
SymPhas—General purpose software for phase-field, phase-field crystal and reaction-diffusion simulations, Steven A. Silber and Mikko Karttunen, Adv. Theor. Sim. 5, 2100351 (2022). Preprint: arXiv:2109.02598 Article accepted for publication in Advanced Theory and Simulations (Nov 2021) Introduction...
[355] implemented the phase-field method in a staggered scheme to sequentially solve for the displacement, phase-field, and fluid pressure. Asymmetric deflection along material interfaces and penetration of hydraulic fractures in naturally-layered porous media were reported for different layer arrangements...
然而,在实际实现中,过渡区的厚度比实际系统中的厚度大得多,并且我们不清楚在保持热力学条件而产生的人工厚度的正确性是否比以其他方式模拟过渡区行为的方法具有任何优势。相场方法在凝固模拟中得到了广泛的应用,但其在流体动力学模拟中的应用更为有限。 为了更新识别不同流体的相函数c,在对流方程中添加了一个非线性...
A new phase-field modeling framework with an emphasis on performance, flexibility, and ease of use is presented. Foremost among the strategies employed to fulfill these objectives are the use of a matrix-free finite element method and a modular, applicat
