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.
