The code uses mostly the same physical models as XFOIL to perform coupled inviscid-viscous analyses, with changes in the solver, stagnation-point treatment, and transition prediction. However, it differs in code layout, modularity, and choice and scope of variables. Furthermore, while written in an interpreted language, it takes advantage of Matlab's powerful linear algebra capabilities to prevent excessive computational costs. A graphical user interface reduces the learning curve, whereas the class structure enables direct embedding in other scripts. Examples in this paper demonstrate these capabilities, offer directions for extensions of the code, and present one such extension: adaptive paneling driven by an output error estimate. 收起
