MARS discretization scheme
 

Hi!

I am working in a problem of instationary mass transfer between two inmiscible liquids. The both liquids are separated by a wall type boundary, which becomes the value of the concentration in the interface calculated through the value of the concentration in the next cell.

If I use MARS discretization the solution has an ondulated concentration profile, and taht does not happen when I use other discretization schemes... do I need to define the boundary conditions in another way?

Thank you in advance.
