PRESTO! Order of Accuracy
 

What is the formal order of accuracy for the PRESTO! discretization scheme?

The fluent theory guide and user guide provide almost no information. Are there any credible sources available about this scheme?

Many thanks!

high order scheme uses the discrete continuity balance for a “staggered” control volume about the face to compute the face pressure.
