Pagination or Media Count:
In the finite element approach to static structural analysis, the solution of the equation KU P a positive definite system of simultaneous linear equations, is basic. Considerable difficulty may be experienced when K is very large and sparse. The report documents an investigation of several FORTRAN subroutines in order to obtain an efficient Cholesky algorithm subroutine with economical core storage for an in-core solution of KU P for large sparse K.
