In mathematics, the method of characteristics is a technique for solving partial differential equations. Typically, it applies to first-order equations, although more generally the method of characteristics is valid for any hyperbolic partial differential equation. The method is to reduce a partial differential equation to a family of ordinary differential equations along which the solution can be integrated from some initial data given on a suitable hypersurface. This software is an example of implementation of characteristics method in a definition of convergent-divergent nozzle.

说明：  newmark法计算多自由度响应，输入刚度、质量、阻尼矩阵，还有激励矩阵，即可求出响应(The Newmark method is used to calculate the multi degree of freedom response. The response can be obtained by inputting stiffness, mass, damping matrix and excitation matrix)
