DB Guest Posts: n/a	Hi All, I wish to know the difference between pressure based solver(eg. star-CD) and density based solver(Fluent). As far as I know both of them use finite volume formulation and use spatial and temporal discritisation(usually implicit)and then use pressure correction schemes(SIMPLE,SIMPISO or PISO) to convert non-linear system of algebraic equations to linear system of equation. These equations are then solved iteratively using Conjugate gradient method or multi grid techniques. DB
