AbstractThe 'Post Limiter (simple a posteriori slope limiter),' which tries to keep spatially second order as much as possible, has been successfully extended to three-dimensional (3D) unstructured grids. Then, this 3D-extended version of Post Limiter ('Post Limiter 3') has been incorporated into 'FaSTAR,' a 3D unstructured grid flow solver. By taking account of cell-geometric qualities (i.e., aspect-ratio-like number), the Post Limiter 3 can handle general 3D cells including 'dirty' (=ill-shaped) ones in which the original Post Limiter fails to continue flow computations. Numerical examples demonstrate its applicability to a wide spectrum of aerodynamic problems of high engineering importance.
