Journal of Software, 2006,17(3):568−576. /1000-9825/17/568.htm Abstract: This paper, solves the 3D fluid dynamics problem in a complex environment by taking advantage of the parallelism and programmability of GPU (graphics processing unit). In difference from other methods, innovation is made in two aspects. Firstly, more general boundary conditions could be processed on GPU in the method. By the method, the boundary from a 3D scene with capped solid clipping is generated, making the computation run on GPU despite of the complexity of the whole geometry scene . Then
