Adaptive Double-Diffusion Model and Comparison to a Highly Heterogeneous Micro-Model

Figure 3

Numerical approximation at 𝑡_𝑛=3×10⁻² of (a) and (b) the solutions of the two components of the macro-model (4.2) and (c) the solutions of the micro-model (2.8a) and (2.8b). Figure (d) shows the side view of (a, b, c) at 𝑦=0.4 and 𝑦=0.5. Data from Example 3.2 with 1/𝜀=5 and ℎ=ℎ₁=ℎ₂=1/50.
