Multi-level solution of the elastohydrodynamic line and point contact problems

This paper describes a fast numerical solver for the elastohydrodynamically lubricated circular contact problem. As a result of the application of multigrid techniques the algorithm is of very low complexity, ie. O(n In n), where n is the number of nodes on the grid. Consequently, it enables the solution of the problem using large numbers of nodes (O(10’)) on a small-capacity computer, as is demonstrated by the results presented for an example load situation. 1
