Abstract A new and computationally efficient version of the immersed boundary method, which is combined with the
coarse-graining method, is introduced for modeling inextensible filaments immersed in low-Reynolds number
flows. This is used to represent actin biopolymers, which are constituent elements of the cytoskeleton, a complex network-like structure that plays a fundamental role in shape morphology. An extension of the traditional
immersed boundary method to include a stochastic stress tensor is also proposed in order to model the thermal
fluctuations in the fluid at smaller scales. By way of validation, the response of a single, massless, More >
