FCT_VOF-and-Youngs
FCT_VOF AND YOUNGS_PLIC fully functioning source codes Debugged and fully functioning source codes Both can be used to calculate by choosing the icase for (1) the Zalesak rotational flow problem (2) the shear flow problem This complete set includes both FCT_VOF and Youngs_plic source code in f90. Including a input data file. The codes have been debugged and tested using MS-FORTRAN. Results can be obtained directly from the output files and loaded to get results.

其基本思想是取B样条函数为及基函数，在[a,b]中均匀划分区间，xi=a+ih,h=(b-a)/n,由于三次样条函数空间是n+3维的，所以把分点扩充到x-1,xn+1,则任意三次样条函数可用线性组合来表示：(The basic idea is to take B-spline function and basis functions in [a, b] in the evenly divided intervals, xi = a+ ih, h = (ba)/n, because the cubic spline function is n+3 dimensional space , so the expansion points to the x-1, xn+1, then any cubic spline function can be expressed as a linear combination:)
