# SIMPLER algorithm - SIMPLE - Revised

The revised algorithm consist of solving the pressure equation to obtain the pressure field and solving the pressufre-correction equation only to correct the velocities. The sequence of operations can be stated as:

2. Calculate the cofficients for the momentum equations and hence calculate $\hat{u}, \hat{v}, \hat{w}$ from momentum equations by substituting the value of the neiboughbor velocities $u_{nb}$

3. Calculate the cofficients for the pressure equation, and solve it to obtain pressure field

4. Treating this pressure field as $p^{*}$, solve the momentum equation to obtain $u^{*},v^{*},w^{*}$

5. Calculate the mass source $b$ and hence solve the p^{'} equation

6. Correct the velocity field by use, by not do not correct the pressure

7. Solve the discretization equations for other $\varphi$ if necessary
