Detailed Description
Poisson step of the Chorin and Temam fractional step method.
- Note
- Chorin and Temam fractional step sscheme to solve the incompressible Navier-Stokes equations [13] [23]
- (1) Prediction: the momemtum equation is solve from a pressure guess
- (2) Poisson: solve the Poisson equation
- (3) Correction: correct the pressure and velocity to get a divergence free velocity field
