CALCULATING DEVICE FOR SIMULTANEOUS LINEAR EQUATIONS

PURPOSE:To provide the device effective for analyzing simultaneous linear equations of large scale on a parallel vector computer, especially, effective for the triangulation of a skyline matrix obtained by structural analysis using the finite element method. CONSTITUTION:This calculating device for simultaneous linear equations calculates the solution of the simultaneous linear equations with the skyline matrix provided by the structural analysis using the finite element method provided by the structural stores the coefficient matrix A given by one- dimensional arrangement the leading address table NP of the respective columns and the right side vector B of A, and performs processing separately for the case where the heads of skylines are equal for (1) pieces (1=2, 3, ..., 6) and the other case corresponding to the value of the NP. Therefore, the parallel vector computer enables high-speed calculation 7-20 times as fast compared to the conventional system.
