Numerical and theoretical studies of pattern formation in a variety of nonlinear, nonequilibrium dynamical systems will be studied. These studies include the kinetics of phase separation in binary alloys, polymer blends and block copolymers. Additional topics include Rayleigh Benard convection in pure fluids and reaction- diffusion phenomena in chemical and biological systems. These studies involve application and improvement of algorithms developed in prior work. As such, algorithm development for massively parallel computers is included to facilitate the solution of some of these problems. The grant is funded through the Materials Theory program in the Division of Materials Research and the New Technologies program in the Division of Advanced Scientific Computing.

在各种非线性、非平衡动力系统中模式形成的数值和理论研究将被研究。这些研究包括二元合金、聚合物共混物和嵌段共聚物的相分离动力学。其他主题包括纯流体中的瑞利贝纳德对流和化学和生物系统中的反应扩散现象。这些研究涉及应用和改进在以前的工作中开发的算法。因此，包括大规模并行计算机的算法开发，以促进其中一些问题的解决。该基金由材料研究部的材料理论项目和高级科学计算部的新技术项目资助。
