The proposed approach is validated by its application to simulate transonic flows over a NACA airfoil. It was found that the present mesh-free results agree very well with available data in the literature, and the implicit LU-SGS algorithm can greatly save the computational time as compared with explicit time marching by:   Consider a triangle abc in a two-dimensional space () A gridless Euler/Navier–Stokes solution algorithm for complex aircraft applications.
