I am using roe scheme coupled water volume fraction to calculate the free surface problem.But after interation,the water volume fraction is outside of the physical boundedness.I just give it greater than 0 and less than 1,is it right?Hirt has mentioned a donor and acceptor method.What about other ways to solve this problem? Thanks in advance!

A paper uses roe +MUSCL + artificial compressibility + VOF idea is: Pan D and Chang C-H. The capturing of free surfaces in incompressible multifluid flows, Int J Num. Meth. Fluids, Vol.33, pp. 203.
