Parallel Agglomeration Strategies for Industrial Unstructured Solvers

摘要

An industrial aerospace code has been parallelised for execution on shared memory and distributed memory architectures. The flow solver uses an explicit time integration approach and utilises an agglomeration multigrid strategy to accelerate the convergence. A novel method has been used that efficiently parallelises the niultigrid solver and also minimises any intrusion into the flow solver. The parallel code uses standard message passing routines and is demonstrated to be portable.
