Cartesian grid method is suitable for aerodynamic design of aircraft because its fast, automatic and robust grid generation alleviates labor and time in numerical simulation. To improve simulation accuracy near wall in Cartesian CFD, we have proposed the method which extends wall adjacent fluid cells to the wall. Thus, conservation laws are satisfied, and wall aligned grid can be generated without complicated exception handling on arbitrary shaped objects. The objective of the present study is to examine the applicability of our method to grid generation around 3D complex geometries. The grid around DLR-F4 is generated and shape reconstruction quality is examined. In addition, inviscid flow calculations around NACA0012 and ONERA M6 are conducted.
