SIMPLE(Semi-Implicit Method for Pressure Linked Equation) Algorithm

1. Flow Equation 2. Algebraic Equation 3. Calculate u and v from initial condition
4. Calculate pressure corrected field 5. Calulate velocity from pressure correction field

SIMPLE Algorithm Sequence

STEP 1. Initial guess P*, u*, v*

STEP 2. Solve discretised momentum equation


STEP 3. Solve pressure correction equation


STEP 4. Correct pressure and velocities


STEP 5. Solve all other discretised transport equation


STEP 6. Convergence Check

STEP 7. If 'yes' then STOP, or set P=P*, u = u*, v = v* and go to STEP 2.
