SIMPLE——From User Guide

The sequence for each iteration follows:

  1. Advance to the next iteration $ t^{n+1}$​
  2. Initialise $ u^{n+1}$​ and $ p^{n+1}$​ using latest available values of u and p
  3. Construct the momentum equations
  4. Under-relax the momentum matrix
  5. Solve the momentum equations to obtain a prediction for $ u^{n+1}$
  6. Construct the pressure equation
  7. Solve the pressure equation for $ p^{n+1}$
  8. Correct the flux for $ ϕ^{n+1}$
  9. Under-relax $ p^{n+1}$
  10. Correct the velocity for $ u^{n+1}$
  11. If not converged, go back to step 2
