This study, by applying the finite element method for incompressible viscous fluid, calculated using the GPU. In order to perform calculations on GPU, using the CDS format for sparse matrices. The CDS format, can be calculated for high-performance vector computers. Numerical examples, the problems 3D Cavity flow, steady state at Re = 1,000 and non-steady state at Re = 3,200 is calculated. Appleyed the number of nodes is calculated by 32 x 32 x 32, 64 x 64 x 64 and 128 x 128 x 128 hexa mesh. The matrix solution, results calculated using the method measures the rate of conjugate residual (CR) method, part of the SpMV, calculated by the performance of the 36Gflops. This approach, by finite element method for fluid analysis, proved to be a high efficient method for calculating the GPU. These results were obtained CUDA version 4.0 using a NVIDIA GeForce GTX580 1.5GB memory.
