Line 96:

# First the system is progressed in time to a mid-time-step position, solving the above transport equations for mass and momentum using a suitable advection method. This is denoted the ''predictor'' step.

# At this point an initial projection maybemay be implemented such that the mid-time-step velocity field is enforced as divergence free.

# The ''corrector'' part of the algorithm is then progressed. These use the time-centred estimates of the velocity, density, etc. to form final time-step state.

# A final projection is then applied to enforce the divergence restraint on the velocity field. The system has now been fully updated to the new time.
