Parallel Fluid-Structure Interaction Simulation

In this work we implement the parallelization of a method for solving fluid-structure interactions: one-field monolithic fictitious domain (MFD). In this algorithm the velocity field for solid domain is interpolated into fluid velocity field through an appropriate L-2 projection, then the resulting combined equations are solved simultaneously (rather than sequentially). We parallelize the finite element discretization of spatial variables for fluid governing equations and linear system solver to accelerate the computation. Our goal is to reduce the simulation time for high resolution fluid-structure interaction simulation, such as collision of multiple immersed solids in fluid.
