Abstract

Splitflow, a Cartesian grid computational fluid dynamics (CFD) code, has been developed for analysis of complex tactical aircraft configurations. Splitflow possesses a single tree-based grid structure that combines the advantages of both binary tree and oct-tree grid systems. The omnitree gridding technique is described, along with an explanation of the numerical methods and various features of the code. Results are included which demonstrate omni-tree Splitflow's ability to automatically capture complex geometries and flow features for Euler analyses. Turbulent analyses have also been performed on specialized cases where boundary layers are fairly well aligned with the Cartesian coordinates.
