Abstract: In order to solve the large scale structural analysis problems, a finite element solution method called EBE-CG method is presented, which does not require the formation of global stiffness matrix, and then its parallel implementation is discussed. Numerical examples show that the parallel EBE-CG method is very efficient. For example, when the number of elements of the model structural analysis is 1920, the speed of parallel EBE CG method, when 12 PE(Processing Element) is used, is more than 50 times that of conventional serial CG algorithm, which does not utilize the EBE strategy.
