Abstract

The computation of numerical solutions to elastohydrodynamic lubrication problems is only possible on fine meshes by using a combination of multigrid and multilevel techniques. In this paper, we show how the parallelization of both multigrid and multilevel multi‐integration for these problems may be accomplished and discuss the scalability of the resulting code. A performance model of the solver is constructed and used to perform an analysis of the results obtained. Results are shown with good speed‐ups and excellent scalability for distributed memory architectures and in agreement with the model. Copyright © 2006 John Wiley & Sons, Ltd.
