FK^{3} is an in-house flow and flame analysis code, whose development was initiated at the Komori and Kurose laboratory and has been continued at the Kurose laboratory at Kyoto University. The FK^{3} has been originally developed based on a pressure-based semi-implicit solver for compressible flows and recently expanded to a density-based solver. Some achievements obtained using the FK^{3} are as follows.
