Abstract

This paper deals with the problems that occur running large-scale finite element analyses on PC's. In many in-house finite element packages direct solvers rather than iterative solvers are included, because direct solvers are simple to implement and always provide a system solution. For large analyses direct solvers need a lot of memory, which in most cases is not available. Of course creating a swap space is a possibility, but this will slow down a calculation significantly.

To avoid these problems an Element-by-Element Linear Preconditioned Gradient solver is developed on an Intel dual processor PC platform running Windows NT. The performance of this solver is tested on some practical analyses and compared with direct and other iterative sequential and parallel solvers on the same platform.
