maple学习资料，以后学习maple就不用担心了(maple learning materials)

开关电源电感计算案例，buck降压斩波输出电感的参数计算和选型(inductor parameter calculation of switching power supply)

计算光子晶体的源程序，基于fdtd 算法，很有帮助(photonic crystal calculation of the source, based on fdtd algorithm, helpful)

内插高程点，CASS不提供插求高程点功能，我们手工输入容易出错，且极度不方便，。 此程序用VBA编写，界面操作，按设定的比例自动计算需内插的个数并注记。(Interpolated elevation points)

说明：  非线性有限元程序，NONSAP is a general finite element program for the nonlinear static and dynamic analysis of complex structures. The program is very flexible and was designed to be extended and modified by the user. In particular the program can easily be modified to use a different formulation of the equations of motions, different time integration operators and other additional options.
