Abstract
This paper outlines the development and application of a solution-adaptive local grid refinement procedure for numerical fluid dynamic calculations in complex domains involving body-fitted unstructured meshes. A new space discretization practice and an error estimation technique were developed to facilitate adaptive space discretization (h-refinement) using cells of arbitrary topology. The methodology enables implicit, consistent, and uniform treatment throughout the entire computational domain including the interface between refined regions and the rest of the computational mesh. It is demonstrated on a number of test cases involving both laminar and turbulent flows, in which initially regular hexahedral meshes are refined by cell subdivision. Encouraging results are obtained.
