Parallel computations for implicit scheme is very difficult in parallel algorithms of computational fluid dynamics. This paper adopts a so-called local implicit method with the technology of sending/receiving data structure and automatic partition. It effectively realizes the parallel computations for subsonic, transonic and supersonic flows of vehicles under parallel distributed network system with PVM platform, which the parallel results are consistent with serial results. It is a simple and applied method with a high parallel efficiency. The parallel soft has a good transplantability and a far-ranging applications.
