Schematic of the computational biofilm system: The computational domain Ω is assumed to be a rectangle of dimensions L × H. The actual biofilm is the area Ω2(t) = {x : N (t, x) + R(t, x) > 0}, surrounded by the aqueous phase Ω1(t) = {x: N (t, x) = R(t, x) = 0}, spearated by the interface Γ1(t) (not explicitly plotted). The biofilm grows on the bottom boundary, which represents the substratum.
