Extensive isothermal solutions for elastohydrodynamic lubrication (EHL) of elliptical contacts under pure rolling are obtained by using the newly developed finite element system approach. The Hamrock-Dowson type of performance formula is revisited with these close-to-Newtonian results. Additional solutions are also compared with those obtained by a multigrid technique. The current solutions show good agreement with their existing counterparts.
