WebbThe main idea of the PISO algorithm is to move the repeated calculations required by SIMPLE and SIMPLEC inside the solution stage of the pressure-correction equation [ … WebbPISO and SIMPLE are standard CFD solvers for incom-pressible ﬂows and we followed [14, 27] in their implemen-tation. We used the ﬁnite volume method (FVM) to dis-cretize Navier-Stokes equations which are then solved iter-atively until convergence. This iterative procedure consists of a sequence of well-deﬁned steps. For example, PISO share an excel file on google drive
