This work is devoted to the development and testing of algebraic multigrid based
preconditioners for the linearized coupled fluid-structure interaction
problem using low order finite element basis functions,
and the compressible and nearly incompressible
elasticity sub-problems in mixed displacement-pressure form using higher-order
finite element basis functions.
The preconditioners prove to be robust with respect to the mesh size, time step size, and
other material parameters.
