摘要
加密高斯点单元传导矩阵调整法通过加密复合单元内高斯积分点的数目,不仅提高了复合单元的传导矩阵值计算精度,而且还基本上克服了无压渗流场迭代计算过程中自由面的震荡现象。根据该法编制了有限元程序MESeep,并采用该程序进行了实例分析。结果表明。
By increasing the number of Gaussian integrating points, the calculation precision of conductivity matrix of compound elements was improved and the free surface oscillation during the iteration was overcome. Adopting this method, program MESeep was coded and cases were carried out. The results showed that the method and program are feasible.
