So what is have seen are two methods where tthe interface shape is compared after a certain time and the other option is to use Grid Convergence Index (GCI) like described in http://www.grc.nasa.gov/WWW/wind/val.../spatconv.html I am trying to figure out GCI method I got confused after looking at how it is used in literature. So I was hoping someone can help it me out What I understood about GCI is that: Order of grid convergence $p = \text{ln}\frac{f_3 - f_2}{f_2 - f_1}/Big{\text{ln}r}$
