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…

Parallel Algorithms for the Solution of Large-Scale Fluid-Structure Interaction Problems in Hemodynamics

TLDR
A new block parallel preconditioner is developed for the coupled linearized FSI system obtained after space and time discretization, and can be regarded as an alternative to the mortar element method: it combines the accuracy of the latter with the easiness of implementation in a numerical code.
