Solute concentration over time in a 2D problem demonstrating the visualization of a scalar result using a fringe plot. The upper cylinder was initially at a uniform solute concentration of 0 mM, and the bottom plate was initially at a uniform solute concentration of 1 mM. The cylinder was displaced into the plate over the first second of analysis and then allowed to relax (based off analysis by Ateshian et al. [96]; solute solubility κ = 1, osmotic coefficient Φ = 1, diffusivity = 5 × 10^–4 mm²s^–1, free diffusivity = 10^–3 mm²s^–1, permeability 10^–3 mm⁴N^–1s^–1, neo-Hookean solid matrix with E = 1 MPa and ν = 0.3, 3-mm radius of upper disk, displaced downward 1.5 mm, analyzed in FEBio).
