FIG. 7.

Time evolution of the differential surface area S_P (scaled with its original value $S_P^0$) for the spectral discretization point at the middle of the spectral elements for (a) a swollen and (b) an extra swollen erythrocyte tank-treading in shear flow with λ = 0.1 and Ca = 2. Note that out of the N_E = 10 spectral elements used in our computations, only four are independent (and show different behavior) owing to symmetry reasons. With respect to the first cell shown in figure 2(c), the location of the spectral elements presented here is: (——): upper dimple; (– – –): lower dimple; (- - -): edge region below dimple; (– · –): lateral edge.
