用C语言编写的Fluent UDF实例，包含Adjust宏，profile宏等八个实例教程，快速上手(The UDF is for computational fluid dynamics software Fluent, it concludes the Profile.c,the Adjust.c)

和大家分享一个全相位FFT，matlab程序，程序中全相位fft实现方法有两种，注释掉的根据原理推到得来，自己看吧。(And share a full-phase FFT, matlab program, the program fft implementation in all phase two, comment out the basis of the principle pushed to come, see for yourself.)

说明：  摩擦力是抵抗固體表面，流體層和材料元件相對滑動的相對運動的力。有幾種類型的摩擦：幹摩擦是一種與之相反的力(friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the)
