Abstract: In order to create 3D calculation grid, 2D Poisson equation was solved by time matching method. It showed a numerical method to create structure grid of complex region in turbine engine. Perpendicularity and quality of grid was provided betterly by this method. The ability to simulate in detail of flow field would be improved by this method combined with domain decompose method.
