Web4.4 Numerical schemes. The fvSchemes dictionary in the system directory sets the numerical schemes for terms, such as derivatives in equations, that are calculated during a simulation. This section describes how to specify the schemes in the fvSchemes dictionary. The terms that must typically be assigned a numerical scheme in fvSchemes range ... WebThe 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: No under-relaxation is applied. The momentum corrector step is performed more than once.
