Abstract
In this work, a nonlinear block-structured CAA solver, the NASA Glenn Research Center BASS code, is tested on a realistic CAA benchmark problem in order to ascertain what effect the high-accuracy solution methods used in CAA have on a realistic test problem. In this test, the nonlinear 2-D compressible Euler equations are solved on a fully curvilinear grid from a commercial grid generator. The solutions are obtained using several finite-difference methods on an identical grid to determine the relative performance of these spatial differencing schemes on this benchmark problem.Keywords
