摘要：

Despite many researches in the past decades, starvation modeling of an elastohydrodynamic lubricated (EHL) contact is still an arduous task. The well-established Jackobson, Floberg, and Olsson (JFO) theory indeed shows jump discontinuities that are tricky to consider in a numerical solver. Two strategies are discussed in this article. The first one uses a penalty method, while the second one uses a moving mesh method. Their efficiency are compared to reference cases coming from the literature. Then, they are submitted to a transient analysis where the oil inlet layer decreases suddenly.
