Iteration numbers (it.) per Newton step and computational time (in s) per Newton step for the all-floating and the classical FETI approach with quadratic ansatz functions comparing the three considered preconditioners. The penalty parameter κ was set to 1000 kPa. Mesh: mesh of the carotid artery with two layers (adventitia and media) subdivided in 1024 subdomains, calculated with 1024 cores.
