  The dynamic iteration method with a restricted additive Schwarz splitting is
investigated to co-simulate linear differential algebraic equations system
coming from RLC electrical circuit with linear components. We show the pure
linear convergence or divergence of the method with respect to the linear
operator belonging to the restricted additive Schwarz interface. It allows us
to accelerate it toward the true solution with the Aitken's technique for
accelerating convergence. This provides a dynamic iteration method less
sensitive to the splitting. Numerical examples with convergent and divergent
splitting show the efficiency of the proposed approach. We also test it on a
linear RLC circuit combining different types of circuit modeling (Transient
Stability model and Electro-Magnetic Transient model) with overlapping
partitions. Finally, some results for a weakly nonlinear differential algebraic
equations system are also provided.
