Abstract
The steady state solution of the Euler equations is computed in parallel on
CRAY T3E on a structured grid around the M6 wing. The grid is partitioned into
a number of blocks. In each block the grid is refined or coarsened based on an
estimate of the error in the solution. The convergence is accelerated by the
multigrid algorithm. Good parallel speedup is obtained also for the adapted
grids. The combination of parallel computing and adaptivity reduces the elapsed
time with orders of magnitude.
