UPACS (Unified Platform for Aerospace Computational Simulation), which aims to be a common CFD platform, is a solver for compressible flows around complicated geometries using the multi-block structured grid method. In order to ease application to more complicated geometries that are difficult to create structured grid as well as to solve flows parametrically which requires many geometry modifications, UPACS has been modified so that the flow solver can treat the overset grid method and a new program, createOversetIndex, which automatically generates interpolation information on overset grid boundaries from grid files and some user-defined configuration files, has been developed in the year 2000. However, some problems have been found such as the preparation of complicated configuration files when many numbers of grid blocks are used and glitches which sometimes appear near unstructured block-to-block connections. In order to overcome the problem, a new algorithm that can generate more reliable interpolation information without bothering user's hand has been developed then the program createOversetIndex has been substantially modified. In this paper, the algorithm to generate interpolation information is explained, and the numerical simulation result of a film cooling flow model for a turbine blade by the overset grid method is introduced and compared to the result with the boundary fitted structured grid.
