The PISO (Pressure Implicit with Splitting of Operators) is an efficient method to solve the Navier-Stokes equations in unsteady problems. The main differences from the SIMPLE algorithm are the following[1]: No under-relaxation is applied. The momentum corrector step is performed more than once. The algorithm can be summed up as follows: Set the boundary conditions. Solve the discretized momentum equation… Read more →
