An incompressible Eulerian method for fluid–structure interaction with mixed soft and rigid solids

We present a general simulation approach for incompressible fluid–structure interactions in fully Eulerian framework using the reference map technique. The is suitable modeling one or more rigid finitely deformable objects soft with components interacting fluid and each other. It also extended to control kinematics of structures fluids. model based on our previous fluid–soft solver [Rycroft et al., “Reference technique interaction,” J. Fluid Mech. 898, A9 (2020)] generalized by constraining deformation-rate tensor projection framework. Several numerical examples are presented illustrate capability method.
