Schematic of problem setup with domain and interface names. A biofilm (green domain) is grown on the flow cell floor and is interacting with a flowing liquid (blue domain) that is providing nutrients to and also deforming the biofilm which in return is changing the flow field. Undeformed (gray dotted line) and deformed biofilm interface. Inflow (teal) and outflow (yellow) boundaries of the flow cell model are also shown
