FELINE: Finite element solver for hydrodynamic lubrication problems using the inexact Newton method

In this work we present FELINE, a C++ solver of the Reynolds equation for treating hydrodynamic lubrication problems. To correctly describe cavitation regions, FELINE implements inexact Newton iteration (INE) algorithm within finite element method (FEM) framework. The was tested and validated against known cases in literature industrially relevant dimpled textures. Furthermore, provide benchmark complex texture case to evaluate performance robustness implementation. performs very fast when compared with existing implementations shows great degree stability, while providing physically correct solutions thanks INE algorithm.
