Aircraft computations using multigrid and an unstructured parallel library

Crumpton, P. I. and Giles, M. B. (1995) Aircraft computations using multigrid and an unstructured parallel library. Technical Report. Unspecified. (Submitted)



This paper examines the application of unstructured multigrid, using a sequence of independent tetrahedral grids. The test cases examined are for inviscid flow over an aircraft and an M6 wing. The sensitivity of the method to grid sequence and cycling strategy are investigated.

All of the calculations were performed on a parallel computer. This was achieved by using the OPlus library which, by the straightforward insertion of subroutine calls, facilitates parallelisation of the resulting code. A single source OPlus application code can be compiled to executed on either a parallel or sequential machine. This greatly increases the usability of the parallel machine, and the maintainability of the code.
