Abstract: Important concepts such as element vector, pseudo-element valor are discussed and an EBE cpmputational method of preconditioned conjugate gradient method (PCG) is presented, namely EBE-PCG method, which does not require the formation of global stiffness matrix and is highly parallizable. Numerical example shows it is very efficient.

Key words: finite element method, parallel algorithm, structrual analysis
