Several parallel iterative strategies based on domain segmentation were previously developed by the authors. While each is effective, the error distribution after every global iteration is not uniform within each segment, the error being greater at the extremities. A correction to the solution is developed at the interfaces between the disjoint segments which accelerates convergence.
