Figure 5: Simulation results (a–c) of the proposed method ((1a), (1b), (1c)) and (d–g) of the common method ((2a), (2b), (2c), and (2d)), respectively, at time 375 h. The initial condition of the nutrients is given by the blood vessel placed at the right side of the domain. The extracellular matrix is initialised with a constant value. Colouration as given in Figure 3.
