FILMPAR: A parallel algorithm designed for the efficient and accurate computation of thin film flow on functional surfaces containing micro-structure

Abstract
FILMPAR is a highly efficient and portable parallel multigrid algorithm for solving a discretised form of the lubrication approximation to three-dimensional, gravity-driven, continuous thin film free-surface flow over substrates containing micro-scale topography. While generally applicable to problems involving heterogeneous and distributed features, for illustrative purposes the algorithm is benchmarked on a distributed memory IBM BlueGene/P computing platform for the case of flow over a sin...

Nature of problem
Thin film flows over functional substrates containing well-defined single and complex topographical features are of enormous significance, having a wide variety of engineering, industrial and physical applications. However, despite recent modelling advances, the accurate numerical solution of the equations governing such problems is still at a relatively early stage. Indeed, recent studies employing a simplifying long-wave approximation have shown that highly efficient numerical methods are nece ...

摘要
FILMPAR是一种高效且便携的并行多重网格算法，用于求解三维重力驱动连续薄膜自由表面流在含有微尺度地形基板上的离散化润滑近似形式。尽管该算法通常适用于涉及异质和分布式特征的问题，但为了说明目的，该算法在IBM BlueGene/P分布式内存计算平台上针对基板上流动的情况进行了基准测试。
