Convergence of (Soft) Elastohydrodynamic Lubrication Simulations of Textured Slider Bearings

We study the convergence of elastohydrodynamic lubrication (EHL) simulations textured slider bearings. EHL are computationally expensive because equations that describe lubricant film pressure and deformation bearing surfaces coupled and, thus, must be solved simultaneously. Additional simulation requirements, such as maintaining a specific load-carrying capacity or thickness, further increase computational cost they impose additional constraints add converge simultaneously with those surface deformation. methodically quantify bearings function parameters, including different metrics criteria, but also cavitation models, texture design operating parameters. conclude interplay between discretization, metric, criterion carefully considered to implement numerical correct physical solution. Our analysis illustrates well-designed can minimize cost.
