摘要: The solution of elastohydrodynamic lubrication problems is both computationally intensive and industrially relevant. Although the use fast multilevel techniques makes it possible to solve standard EHL quickly, there a need much finer meshes resolve features such as surface roughness. In this paper we investigate adaptive meshing in order focus computational work only on those parts domain where high resolution grid points necessary. results show that mesh adaptation reduces cost while maintaining quality solution.
