Abstract The large-scale numerical analysis in hydraulic engineering gives rise to the need for high-performance computation. To meet it，the algorithm of parallel finite element based on EBE (element-by-element) method is put forward by using J-PCG (Jacobi preconditioned conjugate gradient) method. The algorithm does not invoke any special partitioning of the domain，topology of mesh or element ordering. Global stiffness matrix does not need to be formed and the decomposition of 3D complicate domain can be avoided with this algorithm. A PFEM (parallel finite element method) program is developed and implemented on cluster of workstation (COW). Then it is applied to finite element analysis of arch dam system of the Ertan Project and caverns of the Shuibuya Project. The calculated numerical results show that parallel finite element based on EBE method is applicable for large-scale numerical analysis of 3D structures in hydraulic engineering.
