We introduce a block preconditioner for monolithic 'arbitrary Lagrangian- Eulerian' (ALE) uid-structure interactions based on nite elements. While using this framework all equations arising from uid and structure are treated in a common co- ordinate system. After spatial discretization of the continuous problem by the Galerkin method, the arising system is non-linear and solved by Newton's method. For large problems with many unknowns, at least for 3d problems, good candidates to solve the… Expand
