One of the hypotheses for the mechanism of plaque rupture in atherosclerotic vessels is the circumferential stress within the plaque. The distribution of circumferential stress in vessels can be obtained by using a finite element method. This method is based on dividing a complex structure into a number of but finite small polygons (I.e. elements) composed of several nodes and reconstructing simultaneous displacement equations for all nodes of elements with boundary and loading conditions. To solve these equations and to obtain the stress and strain distribution, all coefficients of the simultaneous equations for the structure have been stored in the powerful and high-speed computers (e.g. supercomputer or workstation) with a large memory. We proposed a desktop system to solve the finite element model by using a personal computer. The skyline method was utilized in this study to save the memory and the processing time.
