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.

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
