2D sections of the first component of the flux field J1, with macroscopic concentration gradient 〈−∇c〉 = (1, 0, 0), obtained by FFT method on the two-scale models (iii) and (iv) used in Section 2.4 at ε = 0.3. The microstructure volume is 300 × 300 × 300 nm3 (9093 voxels at resolution 0.33 nm per voxel). a) Aligned platelets, b) aligned and aggregated platelets.
