FETI Method
Sysala, Stanislav
In this paper we describe the derivation of the standard FETI method and its iterative alghorithm based on the projected conjugate gradient method.We describe the derivation of the FETI method and formulate the original problem as a saddle-point or a dual dual problem.
FETI based solution of contact problems with large displacements
Dostál, Z. ; Horák, D. ; Vondrák, V. ; Dobiáš, Jiří ; Pták, Svatopluk ; Gabriel, Dušan
The paper deals with application of the FETI (Finite Element Tearing and Interconnecting) method to finite element solution of contact problems while taking into account another nonlinearity, namely the large displacements and rotations.
FETI decomposition method applied to solution of contact problem with large displacements
Dobiáš, Jiří ; Pták, Svatopluk ; Gabriel, Dušan ; Dostál, Z. ; Vondrák, V. ; Horák, D.
The paper deals with application of the FETI (Finite Element Tearing and Interconnecting) method to finite element solution of contact problems while taking into account another nonlinearity, namely the large displacements and rotations. We show, in terms of numerical experiments (i) performance of the algorithms stemming from the FETI method, in particular its numerical and parallel scalabilities and optimelity of the dual penalty, and (ii) solution of a Hertzian contact problem, i.e. achieved accuracy of the numerical solution by comparison with the analytical one, and the convergence rate.
