The report presents a method to accelerate convergence of iterative solutions for elliptic and mixed-type partial differential equations. Part two presents shock-fitting method for the line-relaxation solutions to a transonic potential equation. Significant improvements over existing finite-difference methods in speed economy and in accuracy are demonstrated in the framework of transonic small-disturbance theory.
