摘要
首先介绍了有限元和自然边界元的直接耦合法,然后以一个含3个裂纹等截面杆的扭转问题为例编写了并行求解程序,并同串行程序运行时间作了比较,从实践上说明了并行计算在有限元和自然边界元的直接耦合法中的可行性与有效性。
Natural boundary element method（NBEM） and finite element method （FEM） are based on a same variational principle. So they can be coupled naturally and directly. In this paper, the direct coupling was introduced firstly. Then a parallel program for solving the problem of rectangular cross-sections bar with cracks was composed, which was compared with serial program in run time. The availability and effectiveness of parallel computation on the direct coupling of NBEM and FEM was confirmed in practice.
