Lee Safranek: Simulating the formation of biofilms
using the immersed boundary method.
Two simulations are shown of cells in a channel flow that adhere to each other and to the walls if they approach close enough. The bonds also break if fluid shearing forces stretch them enough. The simulation on the LEFT shows "strong" bonds while that on the RIGHT has "weak" bonds.
