AbstractWithin the FETI domain decomposition method applied to nonsymmetric linear systems, a generic set of algebraic parallel global preconditioners is presented. They can be applied to most problems with a saddle-point formulation. An industrial test on a fluid mechanic matrix shows the independence of these preconditioners with the number of subdomains
