In the previous study, the authors proposed high-order finite difference multi-block flow computation technique with the generalized characteristic interface conditions (GCIC) in the structured grid system. The GCIC can realize single point connection between adjacent blocks, and allows metric discontinuities on the block interface, however, the grid points of adjacent blocks have to be collocated correspondingly on the block interface. In this work, in order to enhance the flexibility of the GCIC, by incorporating the high-order interpolation method, multi-block flow computation technique with non-uniform staggered grid connection on the block interface is newly proposed. In this article, their theoretical concept is briefly presented, and some proper numerical test analyses are conducted in order to validate the proposed theory.
