| The first user function (''Sliding_Weertman'') is a non-linear Weertman-type friction law and is described in this page. The second user function (''Friction_Coulomb'') is a non-linear water pressure dependant friction law, as proposed by Schoof (2005) and Gagliardini et al. (2007), and is presented [[:userfunctions:coulomb|here]]. | The first user function (''Sliding_Weertman'') is a non-linear Weertman-type friction law and is described in this page.
