摘要
在求解动力方程过程中,引入多重网格方法,通过多次迭代、逐渐细分网格的方法简化有限元模型的计算,并进行实例分析。研究结果表明,多重网格方法运用灵活、减少运算量、计算简便且具有降噪的优势,这种方法的引入,为地壳运动和形变的研究提供了一个有用的工具。
The method is introduced.Multigri mothod is used during solving the dynamic equations,of which the several times iterative and gradual grid subdivision are used to simplify the calculation of FEM.Its case analysis Shows the multigrid method has the advantages of using flexibly,reducing operand,simplifying calculation and restraining noise.The introduction of multi-grid method provides a useful tool for the study of crustal movement and deformation.
