Validation of the present viscoelastic membrane model against analytical solutions. The steady Taylor shape parameter D of a capsule in simple shear flow at different Ca and ${\eta }^{\ast }$ is compared between our simulations (symbols) and analytical solutions (lines) using the small deformation theory of Barthès-Biesel and Sgaier (1985). The Taylor shape parameter indicates the extent of capsule deformation and is defined as $D=(L-B)/(L+B)$, where L and B are the semimajor and semiminor lengths of the deformed capsule in the plane of shear
