Hi , I am using VOF model with 2 phases and I need to specefy a thin layer in the second phase which has a constant depth "alpha" ...this layer is localized at the interface between the 2 phases and deforms like the free surface ....

-can some body please tell me how to specefy that region ? i need to add source term only for that layer .

thanks Frederic
