Full Newton nonlinear iteration is compared to use of a defect correction approach ((rst order Jacobian, second order residual) for solving the steady state compressible ow equations. The Jacobian is constructed numerically, and solved using a PCG type method with block ILU(k) preconditioning. Numerical tests are carried out using the NACA 0012 airfoil, at(More)
