The dynamic iteration method with a restricted additive Schwarz splitting isinvestigated to co-simulate linear differential algebraic equations systemcoming from RLC electrical circuit with linear components. We show the purelinear convergence or divergence of the method with respect to the linearoperator belonging to the restricted additive Schwarz interface. It allows usto accelerate it toward the true solution with the Aitken's technique foraccelerating convergence. This provides a dynamic iteration method lesssensitive to the splitting. Numerical examples with convergent and divergentsplitting show the efficiency of the proposed approach. We also test it on alinear RLC circuit combining different types of circuit modeling (TransientStability model and Electro-Magnetic Transient model) with overlappingpartitions. Finally, some results for a weakly nonlinear differential algebraicequations system are also provided.
