WebbCONTACT [Vollebregt 2014] include the implementation of a falling friction law and the implementation of an elastic interfacial layer. Likewise, in the simplified theory of rolling contact, which is implemented in the algorithm FASTSIM [Kalker 1982], the influence of water can be considered by adjusting the coefficient of friction in terms of BL. daved griffth owner rated a1
