In this paper an efficient algorithm is designed for decomposition of finite element models, for use in parallel computing. In this algorithm simple concepts of graph theory are employed to partition the FE model into subdomains with approximately equal number of degrees of freedom, while keeping the interface nodes to the smallest possible. Examples are included to illustrate the efficiency of the presented algorithm.
