Overture: Object-oriented tools for solving CFD and combustion problems
The Overture Framework is an object-oriented environment for solving partial differential equations on serial and parallel architectures. It is a collection of C{sup 2} libraries that enables the use of finite difference and finite volume methods at a level that hides the details of the associated data structures, as well as the details of the parallel implementation. It is based on the A{sup 2}/P{sup 2} array class library and is designed for solving problems on a structured grid or a collection of structured grids. This paper concentrates on the implementation of support for the method of composite overlapping grids which the authors use for high-resolution simulations of incompressible and low Mach number hydrodynamics flows in complex moving geometries.
