摘要
当应用有限元法数值求解具有工程应用背景的偏微分方程组时 ,边界条件的合理建模至关重要。总结多年的工程实践 ,从理论高度提出了几个重要的边界条件建模技术 :分解、反求、变换、简约。实践表明 ,这些边界条件建模技术是相当成功的 。
While using the finite element method to solve a partial derivative equation, which possesses a background of engineering application, reasonable model creation of boundary conditions is of supreme importance. By summarizing the engineering practice of many years, several important modeling techniques of boundary conditions: decomposition, inverse solution, transformation, and reduction, have been proposed from theoretical heights. The practice shows that these modeling techniques of boundary conditions are quite successful and possessing value of popularization.
