dc.description.abstract [EN] In this work, the efficient approximation of a nonlinear cardiac poromechanics model is investigated. Quasi-Newton solvers based on iterative two-way and three-way decoupling are proposed. For increased robustness and better performance, the iterative schemes are accelerated by additionally using Anderson acceleration. The solvers are tested for a numerical example simulating cardiac perfusion. The results obtained demonstrate a significant speed-up for the splitting approaches with respect to the standard monolithic Newton method. es_ES
