Computing the flow pattern of blood in the heart is a difficult problem that involves a viscous incompressible fluid coupled to a system of immersed elastic or contractile fibers. The fibers model the flexible heart valve leaflets and the muscular heart wall. The coupled equations of the fibers and the fluid must be solved in three space dimensions and time. A general-purpose computational method for such fiber-fluid interactions is described. The method has been implemented on Cray computers. Implementation details such as vectorization and asynchronous input/output are discussed. Results are presented both for a passive and for a contractile fiber-wound toroidal tube.
