Navier-Stokes solver for problems that may involve relative motion between configuration components. The code uses overset structured grids to accommodate arbitrarily complex geometries while, on a component-wise basis, retain the computational advantages inherent to structured data. Makefiles to compile the software on IBM-SP, Origin 2000, Sun 10000, and Cray T3E platforms are provided with the code. The near-body region includes the surface geometry of all configuration parts being considered and the volume of space that extends a short distance above the respective surfaces. Then, on parallel computers, groups are assigned to processors.
Scalability is realized in a group-wise fashion.
