从一维流体力学拉氏方程组出发,首先构造位移场,然后再利用微分关系式得到各类物理量的表达式,进而构造人为解.该人为解在定义域范围内连续、可微,并且动量、内能方程的源项为0.结合N-R格式,验证了构造人为解的可行性.给出的拉氏人为解,对流体力学拉氏应用程序的正确性验证有重要作用.
In this paper,we constructed manufactured solutions of 1D Lagrangian hydrodynamic equa tions from the various differential relations. The manufactured solutions are continuous. The moment equation and energy equation have no source terms. We applied these solutions to the code with N-R scheme and justify these solution to be feasibility to code verification.
