Abstract

An unfactored implicit time-marching method for the solution of the three dimensional Euler equations on multiblock curvilinear grids is presented. For robustness the convective terms are discretised using an upwind TVD scheme. The linear system arising from each implicit time step is solved using a Krylov subspace method with preconditioning based on an block incomplete lower-upper (BELU(O)) factorisation. Results are shown for the ONERA M6 wing, a wing/body configuration and the NLR-F5 wing with launcher and missile. It was found that the simulation cost is relatively independent of the number of blocks used and their orientation. Comparison is made with experiment where available and good agreement is obtained.
