For the purpose of studying the finite element method in high-Reynolds number turbulent flow, we apply the implicit finite element method and large eddy simulation(LES) In the numerical analysis of turbulent flows, it is necessary to perform large-scale computing, supercomputers are used In this study, numerical analysis using LES-FEM analysis of turbulent flows on the GPU By using the Compressed Diagonal storaged sparse matrix storage(CDS) method for the calculation of the GPU, to speed up sparse matrix-vector product, In addition, to reduce the random access in FEM Numerical examples to compute the channel turbulent flow, and compared with the DNS data, perform the calculation accuracy
