摘要
本文介绍一种求解河道平面二维水流泥沙问题的有限元方法。此法的主要特点是,采用质量集中的简化手段和预报一校正一迭代的时间推进算法,较好地解决了计算储存量和计算速度问题。
This paper introduces a newly developed finte Element Method which is employed in the numerical modeling of river flow and sediment transport. As a distinguishing feature of this method, the problem of storage and time consumption is solved by adopting the simplified measures of mass lumping and the time marching scheme of 'prediction-correction-iteration.'
