Abstract
This paper presents a package of FOTRAN IV subroutines for the out-of-core assembly and solution of a system of linear equations with a non-symmetric coefficient matrix, as met in many finite element applications. A skyline block storage mode is used for the coefficient matrix and a direct triangular decomposition method is employed to solve the system of linear equations. The block partitioning and storage mode of the coefficient matrix and the data transfer procedures for the assembly and solution of the system Ax = b are discussed in detail. Examples from the field of fluid dynamics are presented.
