TLDR
In this article, a capsule is modeled as a liquid drop surrounded by an elastic membrane which follows neo-Hookean law, and the capsule deformation is modelled as a quasi-steady process irrespective of capillary number, viscosity ratio, capsule-to-channel size ratio, and lateral location.About:

Efficient and accurate simulations of deformable particles immersed in a fluid using a combined immersed boundary lattice Boltzmann finite element method
TL;DR: The presented model for small resolutions is investigated to provide a sound basis for efficient but accurate simulations of multiple deformable particles immersed in a fluid and it is concluded that details of the membrane mesh, as tessellation method and resolution, play only a minor role.
